NullPointerException in DefaultHierarchyManager.isExist() while calling from an
EventListener
---------------------------------------------------------------------------------------------
Key: MAGNOLIA-3844
URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-3844
Project: Magnolia
Issue Type: Bug
Security Level: Public
Components: core
Affects Versions: 4.4.5, 4.4.4
Environment: Only tested FreeBSD and Windows XP platforms
Reporter: Ronald Ten Berge
Assignee: Philipp Bärfuss
Attachments: BugTest.java,

HierarchyManagerBug.png
We are using multiple event listeners to export data from Magnolia and we are
seeing multiple NullPointerException in our logs.
The stacktrace for the exception:
Exception in thread "Thread-48" java.lang.NullPointerException
at
info.magnolia.cms.core.DefaultHierarchyManager.isExist(DefaultHierarchyManager.java:399)
at trimm.nxp.wcm.test.BugTest.execute(BugTest.java:14)
at trimm.nxp.wcm.test.BugTest.onEvent(BugTest.java:20)

info.magnolia.module.observation.util.ObservationUtil$ObservationBasedDelayedExecutor$1.run(ObservationUtil.java:361)
at
info.magnolia.cms.util.DelayedExecutor$RunnableWrapper.run(DelayedExecutor.java:104)
at EDU.oswego.cs.dl.util.concurrent.ClockDaemon$RunLoop.run(Unknown
Source)
at java.lang.Thread.run(Thread.java:662)
The cause of this Exception lies in the "re.getCause()" call. This method tries
to retrieve the rootCause, but the rootCause is null (see the attached
screenshot).
The attached class uses the data workspace and triggers this bug when running
using the observation module (configuration export attached).
