slf4j linking error ?

[tom.baeyens]

I'm going to fix the JcrDbTest. This is the exception it currently generates:

Did anyone see such a problem before? It seems like a library incompatibility problem to me between slf4j and log4j.

[tom.baeyens]

found this

I was having the same problem and I solved it by downloading an older
version of slf4j.


the version of slf4j-api shipped with hibernate is 1.5.2 (lib/common/
slf4j-1.5.2.jar)

I downloaded the same version of slf4j from here: http://www.slf4j.org/dist/
and the problem is gone.

[JBPM-1720] update to sl4j-1.5.5

With sl4j-1.5.5 in place the issue does not show any more - for me.
