Description PrplHaz4 2014-07-22 14:04:48 UTC 
This bug was originally marked as duplicate of bug 232939, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

Just realized I was in the middle of a CTRL-Z undoing a few steps - maybe ~10 lines of code.

Analyzing issues from 8.0:

The 20+14s in http://statistics.netbeans.org/exceptions/exception.do?id=732140 report is caused by org.netbeans.modules.j2ee.ddloaders.multiview.EjbJarMultiViewDataObject doing some wild things in constructor.

The 20+2s in http://statistics.netbeans.org/exceptions/exception.do?id=732091 are somehow caused by option dialog, but it has been fixed meanwhile. Now the creation runs off the queue.

http://statistics.netbeans.org/exceptions/exception.do?id=731626 and
http://statistics.netbeans.org/exceptions/exception.do?id=731788 and
http://statistics.netbeans.org/exceptions/exception.do?id=731851 are slow classloading and that is something we don't address per decision of performance team. 

So realistically, the only thing that can be fixed is the slow EjbJarMultiViewDataObject constructor - don't mess with projects in it, please.
Comment 4 Martin Fousek 2014-08-08 07:19:48 UTC 
There are many new reports, I'm going to fix EJB issue to remove this "umbrella" bug, but for now the latest reports:

slow classloading/filesystem:
732521, 732570, 732573, 732635, 732849, 732855, 732969, 732999, 733137, 732898

passing to JPA for further investigation:

Comment 5 Martin Fousek 2014-08-08 09:35:20 UTC

Integrated into 'main-silver', will be available in build *201408090001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
