The new tests added by JEP 425 for this thread dump format search the JSON text for strings but don't parse it completely.  These tests can be improved with a test class that parses the thread dump.

It would be useful if ThreadDump.java contained a comment with a description of the JSON file syntax. It could either be in the form of a simple dump or as a simple syntactic description.
