Snapshot that produce the exception

Starting from NB 7.2 it is impossible to display snapshot created on fly and cannot load snapshots created in NB 7.1.2.

Following exception is produced in both cases:

See attached snapshot file as example.

After quick investigation it seems that bug is somewhere in the method PrestimeCPUCCTNodeBacked.setSelfTimeNode: 

it should not try to invoke container.getSelfTime1ForNodeOfs(ofs) if CPUCCTContainer.collectingTwoTimeStamps flag is false.

Please, note that this is showstopper for ME SDK product.
