Comment 3 David Kaspar 2007-01-09 16:43:18 UTC 
The deadlock was could by:
1) while loading of a document, the Designer class is locked
2) during the loading, missing library libraries are added into project
(J2MEProjectHelper.addLibrariesToProject method) which requires writeAccess on
project Mutex
3) Another modules are locking the mutex first and then there locking the
Designer class -> deadlock

The bug is fixed by post-poning of adding of missing-libraries to request
processor, which is called without Designer being locked
