Description David Konecny 2010-04-07 02:54:13 UTC 
While testing bug 180583 I got completely different errors. I created new Web Project and used Entity from DB wizard to generate entities for all DBs from sample DB. The operation was very slow - several minutes and I noticed that IDE output contained dozens to exceptions:

INFO [com.sun.tools.javac.processing.JavacProcessingEnvironment]: 
 Annotation processing error:
java.lang.IllegalArgumentException: sibling == null
org.netbeans.modules.java.source.parsing.OutputFileManager.getFileForOutput(OutputFileManager.java:183)
[...]

I followed with EJBs from Entity wizard and similarly the process was even slower. The same exceptions were thrown and after a while OutOfMemory exception was thrown. IDE log with exceptions attached.

I saw these exceptions before but without OutOfMemory.
Comment 3 Tomas Zezula 2010-04-07 07:27:25 UTC 
I will look at this.
Comment 4 Sergey Petrov 2010-04-07 08:04:38 UTC 
If it will be hard to do something on ap side, may be disabling ap processing during entity generation can help.
Comment 5 Tomas Zezula 2010-04-07 18:44:18 UTC 
I've fixed the exceptions. The OOM is PermGen, right?
Probably eclipselink does lots of intern, I've downloaded sources to take a look.
Comment 6 Tomas Zezula 2010-04-07 18:56:12 UTC 
One question, does the wizard all modification using runModifiacationtask or does it also some changes without the lock?
Comment 7 Sergey Petrov 2010-04-07 20:25:32 UTC 
main code for entity from db generation is located in org.netbeans.modules.j2ee.persistence.wizard.fromdb.JavaPersistenceGenerator::runImpl()
and looks like main generation is with runModificationTask usage. But can't say if something is done without a lock, need to verify.
Comment 8 David Konecny 2010-04-07 21:47:02 UTC 
Disabling EclipseLink annotation processor (via project's UI) make the problem go away.
