Please review this version string parsing fix for Runtime.Version.
From the bug:

optionally followed by pre-release and build information, in one of the
So an example of "10--ea" does not confirm to any of the above regex's."
For "10--ea", the leading '-' gets picked up, and OPT (which allows the
'-' character) gets set to "-ea". So the pattern matching of the
elements appears to happen as intended.
A case can be added in the parse() code to disallow this (case #2 with
an OPT present, but no PRE).
