Java Development Tools

Hi,

I'm getting a strange exception after rebuild any java class in my app while my web app is in debug mode with integrated server in JDeveloper 11.1.2. In "Debugging:Intergrated WebLogicServer Log" just after rebuild class i get a message "Redefined all recompiled classes that are loaded in the debuggee process." And after that if i try to click to any adf web component or reload a page, i'm getting the error 500 with next stacktrace:

<25.07.2011 22:47:43 MSD> <Notice> <Diagnostics> <BEA-320068> <Watch 'UncheckedException' with severity 'Notice' on server 'DefaultServer' has triggered at 25.07.2011 22:47:43 MSD. Notification details:

With previous releases (11.1.1.3-5) degug mode with Integrated WebLogicServer for my webapps works fine.
Does anyone have any idea for the reason and solution of this problem?

Thanks.
