Hi, Has Nashorn's behaviour for dumping bytecode changed in JDK9?
Given this JavaScript: https://gist.github.com/chriswhocodes/bfe139592adb846967d8 Executed using $JAVA_HOME/bin/jjs -co --dump-debug-dir=. run.js Under 8u60b18 the bytecode is produced as expected: https://gist.github.com/chriswhocodes/e3a85c3613b084e45356 This visualises correctly in JITWatch[1] and the bytecode maps back to the source as expected. But under 9b67 only a small amount of bytecode is output that doesn't represent the source program: https://gist.github.com/chriswhocodes/c6c6e33e7994c98d4975 The correct program output is produced under both executions so I don't think the difference is down to dead code elimination. Possible regression? Thanks, Chris @chriswhocodes [1] https://github.com/AdoptOpenJDK/jitwatch
