RFR: 8216407: java.util.UUID.fromString accepts input that does not match expected format

[Chihiro Ito]

Hi,

I tried to correct this problem.

Could you review this fix, please?

According to the RFC 4122, UUID has a fixed format. I tried to raise an
exception if a string was specified that is not suitable for this
format. Also, is there anything else I should be aware of with this bug?
