Hang in Felix: thread owing a bundle lock waits for ever to lock it again
-------------------------------------------------------------------------
Key: FELIX-2598
URL: https://issues.apache.org/jira/browse/FELIX-2598
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: framework-3.0.2
Reporter: Sahoo
Assignee: Richard S. Hall
Fix For: framework-3.2.0
In GlassFish, I detected a hang. PFA jstack output. The scenario happens like
this:
a) I updated a bundle using telnet console. This thread is holding the bundle
lock.
b) Upon receiving the UPDATED event, one of our extenders bundle enhances the
bundle and calls PackageAdmin.refreshPackages(bundle).
c) PackageAdmin thread holds the global lock and tries to hold the bundle lock,
which is currently held by telnetconsole thread.
d) telnetconsole thread is waiting indefinitely to obtain the bundle lock.
