Error Message: A SIGSEGV is received early in the JVM startup, possibly even when a user attempts to run "java -version". This APAR only occurs on the x86/amd64 platform. Analysis with a debugger will show that the cause of the crash was a SIGILL on an AVX instruction. Stack Trace: N/A .
Local fix
This issue can be worked around using the environment variable TR_DisableAVX=1
Problem summary
