In internal defect at com.sun.tools.jdi.ReferenceTypeImpl.visibleFields(ReferenceTypeImpl.java:394)
It's likely caused by a faulty implementation in Nokia SDK, at least one item returned from inheritedTypes() had to be null.
It's likely, that
JDWP.ReferenceType.Interfaces.process(vm, this).interfaces
returned an array with null element(s).
