Eclipse Bug: Unhandled event loop exception No more handles

Question

I\'ve built a GUI using Swing and the MigLayout.

I am using Eclipse 4.2.2 (64-bit) on Windows 7 Ultimate. Every time I click back into the window to edit my code, a

The 'bug' is discussed here https://bugs.eclipse.org/bugs/show_bug.cgi?id=402983. A lot of discussion around 'multiple monitor' set-ups. I experienced the problem today(click in Eclipse (off-the-shelf ADT v22.3.0-887826) Package Explorer then click in java editor, and the "no more handles" error appears). It makes Eclipse unuseable.

Got me thinking that it is a monitor/graphics card problem on my win7 64bit PC, rather than a problem with Eclipse. I re-installed the graphics card (nVidia GTX480) and updated the drivers. Noticed multiple error dialog boxes(samsung monitor not found) relating to my monitor(in fact a single BX2440 monitor set-up) as i closed the system down for reboot. So, on re-boot I upgraded the monitor driver. Then booted again, and the problem has gone(at least for now).

BTW, I don't have Win 7 SP1 installed, so i don't think the 'full Windows update' solution discussed elsewhere on SO necessarily works for everyone.

Answer 2

Happens with Eclipse Mars.2 Release (4.5.2) and Multimon TaskBar 2.1 on a dual monitor setup, too. It disappears if MM TaskBar is un-loaded.

UPDATE

Still the same with Oxygen.2 Release (4.7.2).

Answer 3

I have the same problem. It is caused by a screen capture software hypersnap7. So I think the hotkey conflict is the reason. Reboot computer, don't start other software, start Android Development Tools and watch which software triger the bug.

Answer 4

I am running dual monitors and have had this issue with both Kepler and STS 3.4.0. Killing the HydraDM.exe process worked for me.

Answer 5

There is a workaround: Change the Java editor to WindowBuilder.

Eclipse → Windows → Preferences → File Associations →, choose WindowBuilder Editor as Java default editor.
