> I just got a deadlock at startup when starting the launchpad integration tests instance on sling trunk revision 1632058 (so starting with Oak):
> {code}
> export DBG="-Xmx1G  -XX:MaxPermSize=256m -agentlib:jdwp=transport=dt_socket,address=30303,server=y,suspend=n"
> export MAVEN_OPTS="-Xmx1G  -XX:MaxPermSize=256m $DBG -Dsling.run.modes=oak"
> cd launchpad/testing
> mvn launchpad:run
> {code}
> I'll attach the stack trace. The discovery HeartbeatHandler, and DiscoveryServiceImpl classes are involved.
> The deadlock happens often on my box (macosx 10.9.5, java version "1.7.0_45"), with the same deadlock pattern AFAICS.
