A DESCRIPTION OF THE PROBLEM :
The code used to access dll's using COM object (such as jacob, jdic or custom dll) doesn't work on 1.6.0_10 jvm. The same code doesn't experience any problem on previous updates. The application sometime doesn't produce errors and never produce jvm dumps: the dll call seems lost and the app keeps working. In the case of jacob library, interacting with MS Word, an exception is raised while trying to use the ActiveX component.
