Hi recently i have shifted from indigo to juno. With juno there is a problem. For every 2 min it says "Unhandled Event Loop Exception" and gets shutdown. So I got irritated and downloaded "Kepler" thinking that this might have solution. But with this also it is the same problem. Is there any way to get out of this or I have to get back to "Indigo" again.

How to resolve this?


Thanks and Regards,
Muralidhar Yaragalla.

Do you really think threatening to move to Netbeans can speed up the process? Or whining on a Monday morning because of no response from a Friday post?

See i don't know who you are. Why should i threaten you. Forum is a public place to discuss anything we like. I am a die hard fan of eclipse. From the very beginning of my career i am with eclipse. But this problem really hurts. for every 5 min my IDE shuts down. Really annoying and irritating. This bug is there in juno but still exist in later release as well (kepler). With this there are only 2 options eighter get back to indigo or leave eclipse. Indigo become too old now so if we can fix and move that's fine or move out of the IDE. There is no choice left. Any way i don't have intentions to threaten any one and there are no people that gets scared. The world is not filled with cowards. so don't worry too much.

IF any one found any work around please post the solution. Thanks in advance.

What platform? What extra plugins? What Java version? We've not seen any
of those in our workspaces so there must be something specific to your
system or the plugins you installed.

The OS is "windows 7". Java version is 1.6. No any extra plugins. First i have installed juno which started this. After that i have removed and installed kepler. Once installation is done i have added few plugins like windowbuilder and few other UML pugins and also updated the existing software. The problem still exist. so i have deleted kepler and just installed the default kepler which i downloaded from eclipse site and also i have changed the workspace but still the problem exist.

Did you try pointing it to an EMPTY completely new workspace? You can
also try removing the workbench.xmi inside your workspace/.plugins/...
folder.

You may want to check to see whether or not you experience the same issues on 3.8. I'm presuming that you have verified that the exact same setup works correctly on Indigo ? it's possible that you were right on the edge of the max number of composites and Juno / Kepler *do* add a few extra layers compared to 3.x (where *everything* was a child of the Shell in what we call "the big lie").
