> Hi,
> I recently converted my unit tests to use a new patch for EasyMock, which 
> utilizes cglib (http://cglib.sourceforge.net/) to intercept calls to classes.
> When I did this, my unit tests which use the online mode (nativehotswap and 
> transparentbootclasspath) started getting errors.
> These errors do not occur when I use AspectJ, or when I use aspectwerkz offline 
> mode.  They are different errors in different cases, but most (not all) seem to 
> relate to a NoClassDefFound exception on this line in the easymock patch:
> Class enhancedClass = Enhancer.enhanceClass(classToMock, null, null, null);
> I have tried explicitly excluding all cglib and easymock packages from weaving 
> in aspectwerkz.xml, but this does not help.
> Any ideas?
