The following error happens when executing a Maven Build (but only if the maven
build runs, the error does not happen when the maven build fails with Bug #2394)
The Error is shown only on the Hudson stdout/err, not within the build console.

Process Explorer shows a Subthread with commandline (Paths shortened and
anonymonized):
java -cp "C:\Dokumente und
Einstellungen\user\.hudson\war\WEB-INF\lib\maven-agent-1.277.jar;C:\maven-2\boot\classworlds-1.1.jar"
hudson.maven.agent.Main C:\maven-2 "C:\Dokumente und

Einstellungen\user\.hudson\war\WEB-INF\lib\maven-interceptor-1.277.jar" 1342

If the maven run is OK, the Subthread terminates. If the maven build fails with
Bug #2394 the Subthread stays in Memory.
