APAR status
Closed as program error.
Error description
Error Message: N/A . Stack Trace: N/A . This APAR adds an experimental option to speed up method invocation using reflection by performing additional inlining. This option is DISABLED by default in Java 6.0.1 and Java 7. The experimental code can be enabled by using: -Xjit:enableFastReflectMethodInvoke This option is UNSUPPORTED unless a customer is directed to use it by IBM JIT compiler support. This feature is planned to be enabled by default in the next major release of Java.
Local fix
Problem summary
Under extreme conditions the performance of a Java application can be limited by the cost of executing methods using reflection.
Problem conclusion
This defect will be fixed in: 6.0.1 SR7 7.0.0 SR6 . When the enableFastReflectMethodInvoke option is in effect the JIT will inline some aspects of method invocation using reflection.
Temporary fix
