User Comments:
GUEST: After few hours of work NetBeans stopped underlining mistakes in source, refactorings became much slower. Tried to relaunch, only to find the process stuck in memory (weighing ~ 850 mb). Had to kill it with task manager

GUEST: Clossing NetBeans

bodonova: Debugging a midlet using  Java ME SDK 3.4. Stopped the emulator. Netbeans popped up an error dialog box stating that there was a deadlock and suggested rebooting the IDE. IDE hung when I exited.

JTD: Even though the AgentToolBox application was terminated gracefully hours before the IDE thought it was still a running process even thouh it was not (I checked the process list as well) so it would not let me terminate the IDE.

GUEST: I was just shutting down NetBeans and I had to force it to close because it said a midlet debugger instance was running (but I wasn't otherwise aware that one was running).

GUEST: Trying to debug into JavaME program using I2C.

GUEST: Clicking everywhere during mobile emulator start.
