Eclipse doesn't work properly anymore [FIXED] [message #913349] Sat, 15 September 2012 06:40 Go to next message

Yesterday, I tried simulating a simple neural network in Java. Everything worked fine, no problems what so ever.

When I started my laptop today and I tried running it again, I got the error:
"An internal error occurred during: "Launching ANN".
com/sun/jdi/connect/IllegalConnectorArgumentsException"

I have never seen this error before.

What's worse, this error now occurs with every project in my workbench, from simple power functions to bigger applications, all worked fine before. The error is exactly the same every time, except that ANN would be replaced with that class' name.

I tried making a new test project, but when I try to run it, nothing happens. No error, but no output either. It doesn't seem to run at all.

I am absolutely clueless about this, but I would love a solution. I have restarted my laptop, and I have tried uninstalling and re-installing Eclipse, both changed nothing for this problem. Google didn't really help me either. I run Ubuntu 12.04, Unity.

Here's a screenshot of the error.

I hope you guys know something!

Are you running against an Open JDK version of Java? Ubuntu broke the
time zone information in the latest Open JDK updated. This causes
strange problems when accessing time related functions.

You can fix the problem by reinstalling tzdata-java.

I don't know if this is your problem or not, but it shouldn't hurt to
try the reinstall.

yep, and the "original" ubuntu bug is https://bugs.launchpad.net/ubuntu/+source/eclipse/+bug/1050404 (fixed).

(I ran into this today, too, Eclipse wasn't its normal self at all ...).

Thanks a lot, Eclipse is back up and running, re-installing the tzdata-java did the trick.
