APAR status
Closed as program error.
Error description
Error Message: Some internally-optimized natives are not instrumentable via JVMTI SetNativeMethodPrefix. . Stack Trace: N/A .
Local fix
Running without the JIT (adding -Xint to the command line) works around the issue.
Problem summary
The name matching algorithm used to optimize certain natives was not taking native method prefixes into account.
Problem conclusion
The JVM now allows instrumentation of almost all natives. A small number of natives inlined by the JIT remain non-instrumentable. . This APAR will be fixed in the following Java Releases: 8 SR3 FP21 (8.0.3.21) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs. For those running stand-alone, information about the available Service Refreshes and Fix Packs can be found at: https://www.ibm.com/developerworks/java/jdk/
