IV67422: GPF IN THE JIT COMPILER

APAR status

• Closed as program error.

Error description

• Error Message: JVM crashes with GPF
  .
  Stack Trace: Corefile analysis will show that the failing method
  isTR_AMD64SystemLinkage::computeMemoryArgSize
  .
  

Local fix

• The javacore will indicate the method being compiled at the time
  of failure (often this will be some form of generated code such
  as from XSLTC). The method can be excluded from JIT compilation
  using-Xjit:exclude={package/className.methodName(*}Nested
  packages are separated using '/', e.g.
  {a/b/c/Class.method(*}Alternatively the problem can be avoided
  by using-Xjit:disableOSR
  

Problem summary

• The problem occurs when compiling a method with a very large
  stack frame while attempting to support the on-stack-replacement
  (OSR) capability that permits transitions from jitted code to
  the interpreter from within the method.
  

Problem conclusion

• The JIT has been modified to cope with very large stack frames
  while preparing for OSR transitions.

  This APAR will be fixed in the following Java Releases:
     7 R1 SR2 FP10  (7.1.2.10)
     7 R1 SR2 FP10  (7.1.2.10)
