Hard crash in JVM

hey,

I have a problem with an instrumentation. When I run instrumented code, the JVM says:

#

# A fatal error has been detected by the Java Runtime Environment:

#

# Internal Error (javaCalls.cpp:53), pid=7268, tid=139709765379840

# guarantee(!thread->is_Compiler_thread()) failed: cannot make java calls from the compiler

#

# JRE version: OpenJDK Runtime Environment (8.0_91-b14) (build 1.8.0_91-8u91-b14-3ubuntu1~16.04.1-b14)

# Java VM: OpenJDK 64-Bit Server VM (25.91-b14 mixed mode linux-amd64 compressed oops)

# Failed to write core dump. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

[thread 139709766432512 also had an error]

If I interpret this error correctly, I somehow got the JVM to execute Java Code on the JIT-Thread.

Do you have any ideas what could cause this, how I could debug this or what else to do about it?

The instrumentation is not that complicated. I just need to do a method call before IF_ICMPEQ instructions.

This method call needs the two inputs to the comparison as arguments, so I am doing some magic with DUP/DUP_X in order to re-arrange

the arguments on the stack as needed. If I, instead of using DUP/DUP_X2 etc. just place constants there and do my method call, it works as expected.

Thanks for your help,

Alex
