A memory leak which affect web services client calls was observed after upgrading to WebLogic 12.1.2 from 12.1.1.

It finishes by a failure because of an OutOfMemory error; the application JVM heap of 1.5G is filled in about 40min.

It looks like the heap contains thousands of objects of type "weblogic.wsee.jaxws.owsm.WsdlDefinitionFeature" .
A WsdlDefinitionFeature object is created for each "createDispatch" method call. (See line 2 of the code)
These objects are never released and do fill the memory.

The following application code triggers the issue:
