Hi All, After much research, we rounded up the problem, this is caused by the API Manager host object using both synapse and jaggery. As I explained in my previous email, when we use two different bundles that use different versions of the same package, inside the same class space, "package use conflicts" are encountered.
As a remedy to this problem, we need to upgrade the org.mozilla.javascript version used by jaggery to version 1.7.0. This will also involve a possible upgrade of bsf versions / changing the synapse ScriptMediator to accommodate for possible API changes. Thanks much, Kisanthan, Ruchira and Manu for all your help.
