------------------------------------------
Summary: when a test's heart beats it should also throw up (dump
stack of all threads)
Key: LUCENE-4510
URL: https://issues.apache.org/jira/browse/LUCENE-4510
Project: Lucene - Core
Issue Type: Bug
Reporter: Michael McCandless
We've had numerous cases where tests were hung but the "operator" of that
particular Jenkins instance struggles to properly get a stack dump for all
threads and eg accidentally kills the process instead (rather awful that the
same powerful tool "kill" can be used to get stack traces and to destroy the
process...).
Is there some way the test infra could do this for us, eg when it prints the
HEARTBEAT message?
