Key: FELIX-3369
URL: https://issues.apache.org/jira/browse/FELIX-3369
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: framework-4.0.2
Reporter: Carlos Quiroz
After upgrading to Felix 4.0.2 from 3.2.1 one of our legacy bundles started
failing to start
After inspection I found a deadlock on
org.apache.felix.framework.BundleWiringImpl
A downgrade to Felix 4.0.1 fixes this problem so I assume the problem started
in 4.0.2
Found one Java-level deadlock:
=============================
"task":
waiting to lock monitor 103072f18 (object 7f4615700, a
org.apache.felix.framework.BundleWiringImpl$BundleClassLoaderJava5),
which is held by "FelixStartLevel"
"FelixStartLevel":
waiting to lock monitor 1030287e0 (object 7f625f8a8, a
org.apache.felix.framework.BundleWiringImpl$BundleClassLoaderJava5),
which is held by "task"
