Description Martin Grebac 2004-05-26 13:06:10 UTC 
java.lang.NullPointerException

Comment 1 Martin Grebac 2004-05-26 13:42:11 UTC 
S**t, problem in my local sources.
Comment 2 Martin Grebac 2004-05-26 13:58:08 UTC 
Well, not a problem in my sources. I was able to reproduce in cont.
build with this scenario:

1. Create web project
2. Put breakpoint into index.jsp
3. Run main prj in dbg
4. When stopped on bp, press F7 (Step into)
First problem - debugger does step to other line, instead the
application runs and jsp is shown in browser
5. Refresh page in browser  - debugger stops on bp
6. Press F8 (Step over)

NPE is written to the console, page is visible in the browser and
application runs
