Unfortunately, the specification is a little bit ambiguous in this matter=
=2E

TSS_HPCRS       hPcrComposite,  // in
Vs.
"On return each element of the collection has its  pcrValue set."

In C this is not much of a problem and easily dealt with pointer=20
assignments. In Java this would require a change to the method's
signature - which I  want to avoid.

Instead I completed the test case with the above example on how to get=20
the PCR values.
