opened on Jul 7, 2017

I've found that perf-map-agent compiled for OracleJDK can crash OpenJDK (usually on the second invocation). I'm changing my tooling so that we have builds for each. This ticket is to suggest that build info is included in the out directory, so that other tooling can double check what it was built against. Eg, just a:

echo JAVA_HOME=$JAVA_HOME > out/build.txt

From the build process would be handy.

For reference, here's stack trace from one of the crashes:

Core was generated by `java -Xms24952m -Xmx24952m -XX:MaxMetaspaceSize=512m -XX:+HeapDumpOnOutOfMemory'.
