Hi,

When execute the junit test we get:

java.lang.IncompatibleClassChangeError at
se.company.wcdma.rbs.boam.pms.impl.RBScanner.preperAndPush(RBScanner.java:526)
at
se.company.wcdma.rbs.boam.pms.impl.RBScanner.scan(RBScanner.java:766)

junit.extensions.TestSetup.run(TestSetup.java:23) 0.086
testOldCounters Error N/A

Any ideas what IncompatibleClassChangeError is and how we can correct it?

Cheers,

The cause for this is probably that the RBScanner classes depends on
another class which has changed. This can happen if you didn't perform
a full recompile of the sources.

Delete your class output, recompile the whole source tree and fix any
errors that pop up

Hi,

Thanks for the reply. We have made a clean of all class files before
doing a full recompile of hte sources. There are not compiling errors.
We still have the problem :-(

More hints appreciated!

What's the code executed on line 526 of RBScanner? It's possible that
there is a difference in used libraries (versions) between the
development and the runtime.

Regards,
Bart
