Jdeveloper 11.1.2.0 & Debug Mode

When you run the application in Debug mode in Jdeveloper 11.1.2.0, compile any java file and refresh the page you get java.lang.NullPointerException.

This issue is discussed in detail at

and the summary is:
------------------------------------------------------------------------------------------
Option 1:  Change Tools->Preferences->Run->WebLogic and setting Select Hot Class Reload Policy to Fast Swap.

Option 2 : Turn off copying of any rebuilt files into the exploded EAR.
Usually the jdev shortcut target will be:
C:\Oracle\Middleware\jdeveloper\jdeveloper.exe

Modify this to C:\Oracle\Middleware\jdeveloper\jdeveloper.exe -J-Doracle.jdeveloper.adrs.incr.buildMonitor=false
and then restart jdeveloper.

Please use option 2 as a last resort. Since the debugger already provides some support for class redefinition, perhaps this will be useful for many who use debug mode.

I set Option 1 and it was working fine. But my weblogic server started crashing intermittently. I'm still working on exact reproducible steps but meanwhile I tried option 2 and it works properly.
