APAR status
Closed as program error.
Error description
Error Message: Failure symptom will be either a performance reduction with increased time spent in the instanceof codepaths or a segmentation error in the JIT compiler code generator while evaluating an instanceof operation on an abstract final class in the JCL. . Stack Trace: N/A .
Local fix
Problem summary
Under certain circumstances the JIT code generator can produce slow or incorrect code when processing classes which are both abstract and final. These classes cannot be generated from user code - this combination can only appear on certain special core classes in the Java Class Library.
Problem conclusion
The JIT code generators have been modified to ensure the code generator correctly handles abstract final classes. . This APAR will be fixed in the following Java Releases: 8 SR2 (8.0.2.0) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
