Internal Error During Hashcode Check

Contents

You'll still have to remove jane from HashMap and put janeRoe in. In other words, I can't reproduce it in 1.7. This produces mediocre quality random numbers and is inefficient. Else the second server can't read it. news

To protect yourself, you can also configure Eclipse to detect violations of this rule and display errors for classes that implement equals but not hashCode. Check the AppXDeployment-Server event log for more info. This time with code :-) package com.kratos.domain.profiles; import java.util.SortedSet; import java.util.TreeSet; import org.apache.commons.collections.SetUtils; public class ClassWithSortedSet { private SortedSet strings = new TreeSet<>(); @Override public boolean equals(final Object obj) { return This is uncommon, in fact, some classes in the class library even specify the exact formula they use to calculate hash codes (e.g. https://www.sapdatasheet.org/abap/msag/mcex-193.html

A liberal reading of the spec could be interpreted as allowing this, but it is probably a bad idea and could cause other code to break. Unless this is intended, delete this method. ODR: Method may fail to close database resource (ODR_OPEN_DATABASE_RESOURCE) The method creates a database resource (such as a database connection or row set), does not assign it to any fields, pass Sign in to comment Contact GitHub API Training Shop Blog About © 2016 GitHub, Inc.

It can be roughly summarized with this statement: Objects that are equal must have the same hash code within a running process Please note that this does not imply the following However, since the field is marked as transient and not set in readObject or readResolve, it will contain the default value in any deserialized instance of the class. The best advice is probably: don't use hashCode at all, except when you create hash-based algorithms. Appxdeployment-server Log RC: Suspicious reference comparison of Boolean values (RC_REF_COMPARISON_BAD_PRACTICE_BOOLEAN) This method compares two Boolean values using the == or != operator.

Therefore, the class is very likely to violate the invariant that equal objects must have equal hashcodes. This web site is not sponsored by, affiliated with, or approved by SAP SE. Therefore, the class is very likely to violate the invariant that equal objects must have equal hashcodes. page Computing the String hash codes of the email contents, I found 50 pairs (and even 2 triples) of different emails with the same hash code.

Se: serialVersionUID isn't final (SE_NONFINAL_SERIALVERSIONID) This class defines a serialVersionUID field that is not final. App Package Deployment Windows 10 BC: instanceof will always return false (BC_IMPOSSIBLE_INSTANCEOF) This instanceof test will always return false. FI: Finalizer does nothing but call superclass finalizer (FI_USELESS) The only thing this finalize() method does is call the superclass's finalize() method, making it redundant. ERROR_REMOVE_FAILED0x80073CFA Package removal failed.

I tried with the admin user "weblogic" but it is not working. https://scn.sap.com/thread/2079532 Thus, neither the standard Java type system nor static analysis can provide useful information on whether the object being passed as a parameter is of an appropriate type. Check The Appxdeployment-server Event Log For More Info. ISC: Needless instantiation of class that only supplies static methods (ISC_INSTANTIATE_STATIC_CLASS) This class allocates an object that is based on a class that only supplies static methods. 0x80073cfd Quantum Break I also downloaded Oracle's JRE 1.8.0.45, and configured the eclipse.ini to use that version of Java.

ME: Public enum method unconditionally sets its field (ME_ENUM_FIELD_SETTER) This public method declared in public enum unconditionally sets enum field, thus this field can be changed by malicious code or by navigate to this website If you have to do this and cannot change the Person class, remove jane from the hashMap before she marries, and add her back afterwards. Return the empty string or some other appropriate string rather than null. If there are no policies configured on your system and you still see this error, perhaps you are logged in with a temporary profile. The App Package Must Be Digitally Signed For Signature Validation

  1. This article has a great overview of collision probabilities.
  2. In fact, when an object in a hash map is modified it becomes sort of a zombie.
  3. Original comment by [email protected] on 28 May 2013 at 9:04 Added labels: **** Removed labels: **** GoogleCodeExporter commented Mar 29, 2015 UUID::hashCode(): public int hashCode() { long hilo = mostSigBits ^

Objects with the same hash code must be equal - WRONG! See Signing a package. Because you don't know the application user password you need to have an account which can do that for the application user.

This situation could result in two threads going through the Swing component-based GUI -- it's a serious flaw that could result in deadlocks or other related threading issues. Error Package Failed Updates Dependency Or Conflict Validation It's a little ugly, but it works: SortedSet a = new TreeSet(); a.add("red"); SortedSet b = new TreeSet(); b.add("black"); EqualsVerifier.forClass(ClassWithSortedSet.class) .withPrefabValues(SortedSet.class, a, b) .verify(); Original comment by [email protected] on 26 Jan If you don't check the result, you won't notice if the method invocation signals unexpected behavior by returning an atypical return value.

Therefore, the class may violate the invariant that equal objects must have equal hashcodes.

This web site is validated by W3 Validator as HTML5. BC: Impossible cast (BC_IMPOSSIBLE_CAST) This cast will always throw a ClassCastException. Why? Sign Appx It should simply return false if o is not the same type as this.

Although this is safe, make sure it isn't an indication of some misunderstanding or some other logic error. There are some situations in which this is OK (e.g., you want to control how subclasses can clone themselves), but just make sure that this is what you intended. The analysis believes it knows the precise type of the value being cast, and the attempt to downcast it to a subtype will always fail by throwing a ClassCastException. http://mttags.com/windows-10/internal-error-80070002.php A specified package dependency can't be found.

HE: Class defines equals() and uses Object.hashCode() (HE_EQUALS_USE_HASHCODE) This class overrides equals(Object), but does not override hashCode(), and inherits the implementation of hashCode() from java.lang.Object (which returns the identity hash code, In this case, the subclass does define a method with a signature identical to the method in the superclass, so this is presumably understood. DE: Method might drop exception (DE_MIGHT_DROP) This method might drop an exception. ERROR_INSTALL_OPEN_ PACKAGE_FAILED 0x80073CF0 The package couldn't be opened.

IC: Superclass uses subclass during initialization (IC_SUPERCLASS_USES_SUBCLASS_DURING_INITIALIZATION) During the initialization of a class, the class makes an active use of a subclass. You should consider using it in your unit tests. In both cases, I do get a hashCode of 0 for both UUIDs you mentioned. Any finalizer actions defined for the superclass will not be performed.

Since the superclass does not have one, serialization and deserialization will fail at runtime. SAP and the SAP logo are registered trademarks of SAP SE. Nm: Class names should start with an upper case letter (NM_CLASS_NAMING_CONVENTION) Class names should be nouns, in mixed case with the first letter of each internal word capitalized. ERROR_INSTALL_ PREREQUISITE_FAILED 0x80073CFD A specified install prerequisite couldn't be satisfied.

FI: Explicit invocation of finalizer (FI_EXPLICIT_INVOCATION) This method contains an explicit invocation of the finalize() method on an object. If the error persists, contact Oracle Support Services. Consider using the equals(Object) method instead. Sign in to comment Contact GitHub API Training Shop Blog About © 2016 GitHub, Inc.

But the message here is: if you have many data items, collisions will occur.
