Changes requested by bchristi (Reviewer).

In the JBS issue, it looks like the Description was put in the Environment.  :)

test/jdk/java/util/regex/RegExTest.java line 291:

Should the message be that they *don't* have equal start indices ?

Should this be:
`assertTrue(m.find() && ng.equals(m.group()));`
