Error description

  • Error Message: A segmentation fault is caught in the J9VM module
    when a JIT compiled method calls a native Java method using JNI.
    .
    Stack Trace: N/A
    .
    The issue only occurs on a 64-bit JVM under the
    -Xnocompressedrefs option. In the register dump generated in
    stderr one or more registers will have 0xFFFF in the most
    significant half-word.
    

Local fix

  • The issue can be worked around by excluding the compilation of
    the method that invokes the problematic JNI call with the
    following JVM option:
    -Xjit:exclude={full_method_signature},dontInline={full_method_si
    gnature}
    Where full_method_signature is the method signature including
    the class path, method name, parameters, and return value.
