Description CMOS 2012-12-31 13:37:50 UTC 
Hello there!

I have a Javafx application in netbeans. My problem is that I have a .java file in a package and when I open it for editing the ide slows down and finally hangs after a while, reporting an warning at the bottom right corner.

"A java.lang.reflect.InvocationTargetException exception has occurred.
However, the system should continue working without further problems."

"java.lang.OutOfMemoryError: Java heap space

When running the project everything works fine. Only when I open a specific .java file it happens. All other .java files I have work normally.

I have noticed that the memory indicator at the toolbar is increasing rapidly when I open that file.

I have tried jdku7, jdk7u10, jdk6u38 cause I thought maybe there was a bug over there.
I tried different computers with the same project

This .java file was a .jsp file before and has almost the same code, just some imports different and some different variables since I was taking some data from a form of a webpage. The .jsp file can be edited normally without any hang ups..

I have tried changing the heap size of the netbeans.conf file but the ide doesn't let me make it higher than 512m.

I don't understand why a file with 400 lines of code can make such a problem..
I have 10 nested for loops. I don't know if that makes any problem.

I mention again that it's slowing down and hanging while opening the .java file and trying to edit not when running the program.

Yes, before fix of bug #223339, deeply nested loops were causing problems.
