Hi,
I have been doing quite a lot of complies of ASJS lately. I encountered about 2-3% of the builds end up with the compiler completely locking up. I used to simply kill them and re-run the build, but this time I used jstack to dump a thread-dump of all threads of that VM. I thought, eventually this could help someone here to track down this problem. I stored the output in the ASF Paste Bucket here: https://paste.apache.org/jgmp Just thought it was worth reporting.
