Re: [eclipse-dev] Ant Editor problem - Save doesn't work and crashes Eclipse

I have logged the following bug report:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=71888

Please CC yourself and in the future use Eclipse's bugzilla for problems such as these.
A sample buildfile and classpath would greatly help in diagnosing the problem.

It would appear that one of the JARs on your Ant runtime classpath has a "bad" or incompatible classfile in it.

The Ant editor should not fail on this.

Thanks

Darins

        Subject:        [eclipse-dev] Ant Editor problem - Save doesn't work and crashes Eclipse



Hi,

I sometimes have problems with the Ant Editor in Eclipse.
On save it pops up an error dialog that tells me something like:
"Save Failed: null"

The log gives the following exception that looks like an incompatible
log4j-Version to me:

I have the Lomboz-Plugin installed, that also installs an
org.apache.log4j plugin

Any Hints appreciated...

Greetings,
   Malte
