workbench and java 1.6 ??

Hi everybody,

I recently upgraded from java 1.5 to 1.6 and since then I have
problems using Mathematica workbench. Basically, debugging doesn't work and I
get error messages like the following. Does this mean the workbench
doesn't work with 1.6 and if yes, where in the workbench do I specify
which jre to use ?

Many thanks,
