Leon created OFBIZ-5625:
---------------------------
Summary: NPE while try to release a service semaphore which does
not acquire any lock
Key: OFBIZ-5625
URL: https://issues.apache.org/jira/browse/OFBIZ-5625
Project: OFBiz
Issue Type: Bug
Components: framework
Affects Versions: SVN trunk
Reporter: Leon
Fix For: SVN trunk
Set a service attribution "semaphore" to "fail" and try to run it twice in
short delay. Since the first one obtains the lock, the second will "fail" and
throws out the "SemaphoreFailException" exception which will be catch in
ServiceDispatcher.runSync method and triggers the semophore.release within that
the NPE occurred because of null lock value.
