Policy based NV read in Java about tss.msr

[amarochk]

Hi Matteo,

The missing policy support is an extra abstraction layer provided in .Net and C++ version of TSS.MSR. All the standard TPM functionality is completely available.

The problem with you code is likely the NV index value. Since you specify the complete index value, including the reserved MSB, you should use TPM_HANDLE() constructor, not the TPM_HANDLE.NV() factory method. With the latter you should use the 0x500016 value (without the MSB 0x01).

Otherwise your code looks good. For the future, when a command fails, the TPM returns an error response code that often is specific enough to pinpoint the source of the problem.
