Oracle 11.1.1.2 XPath issues

Currently I have been migrating BPEL for a client using Oracle SOA Suite and ran into incompatibilities between 11.1.1.1.0 and 11.1.1.2.0. A simple example that worked in 11.1.1.1.0 and not in the latest patched released is a simple evaluation where I am trying to confirm the existence of an element in a message.

<bpws:getVariableData("message","part","/element/element")> = true()

The same statement also works in Cape Clear ESB and its BPEL implementation.

One workaround that I used was to count the nodes using the Oracle XPath Advanced Functions:

ora:countNodes("message","part","/element/element") > 0

I am working with Oracle support services to see how this can be resolved in the code base.
