Has anyone come across a constant "Unhandled event loop exception in STS 3.6.0 Environment: Windows 7 64 bit, new high end PC. 32 bit JVM 1.6

If so can you share the fix(s)?

This is a complete fresh download and install of STS 3.6.0, and I have not coded anything yet, just created an integration project. It is a show stopper as it will not allow me to continue. There is not code to debug as I have not coded anything.

Here is what I did:

  1. Downloaded STS (eclipse) version 3.6.0, installed, configured internet proxy.
  2. Created integration project via boot starter: File->New->Spring starter project.
  3. Left all defaults except selected "Integration" checkbox.
  4. Created everything OK, downloaded all dependencies from Maven.
  5. Ran the project without any changes: demo->run as->Java App, run OK though empty project of course.
  6. I opened Application.java, clicked into it for focus, and hell started.

Had a popup titled "Problem Occurred", with Unhandled event loop exception. No more handles. I hit Ok on popup and second popup appears. Asks if I want to exit workbench as subsequent errors may happen and terminate workbench. Bottom line I am now unable to do anything as popup constantly appears. Same issue exactly on STS version 3.5.1.

I have googled around and seems to happen to LOTS of users but no real resolution.

  • Is there a (programming) question or is this just a rant? – Filburt Jul 15 '14 at 13:34
  • What JVM, and is this 32-bit or 64-bit? – Elliott Frisch Jul 15 '14 at 13:34
  • 32 bit JVM 6.1.0.xxx (not at my machine now...) – user3839560 Jul 15 '14 at 13:39
  • It is a rant unless you have a valid reply. – user3839560 Jul 15 '14 at 13:44

  • Thanks David I did see that, however this is a complete fresh download and install of STS 3.6.0, on a new high end machine, and, I have done no "real" coding, only created an integration project. If I have to do anything beyond an environment / configuration change then I won't bother with STS. I should work without issue for such a basic example, so I can only imagine what would happen if I did real coding. I know it is free I would move to intelliJ or even netbeans rather than put up with these issues (bugs). – user3839560 Jul 15 '14 at 21:35

    OK, so here is the fix, delete eclipse/STS, download IntelliJ, install IntelliJ, as for eclipse...forget about it! – user3839560 Jul 17 '14 at 22:52
  • This looks like a reported Eclipse bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=420561 – Calon Jul 29 '14 at 13:30
