------------------------------------------
Summary: java.lang.IllegalStateException: Can't overwrite cause at
org.apache.directory.server.core.authz.GroupCache.initialize(GroupCache.java:190)
Key: DIRSERVER-1855

Project: Directory ApacheDS
Issue Type: Bug
Components: core
Affects Versions: 2.0.0-M12
Reporter: Konrad Windszus
Priority: Critical
We got the following exception stack trace after trying to start ApacheDS from
a backup:
{code}
14:37:15] ERROR [org.apache.directory.server.wrapper.ApacheDsTanukiWrapper] -
Failed to start the service.

The problem here really is, that this exception hides the real problem here. I
see that even in the trunk you try to set the cause in
http://svn.apache.org/repos/asf/directory/apacheds/trunk/interceptors/authz/src/main/java/org/apache/directory/server/core/authz/GroupCache.java
in the initializeMethod. That is not allowed and leads to that exception if
the original exception already has a cause set
(http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/Throwable.html#initCause%28java.lang.Throwable%29).
Rather just wrap the original exception and leave out the initCause or at
least check first, if the initCause is allowed at that point. Also please
remove the e.printStackTrace as it will land in the standard error stream
rather than in the log.
