[7u12] Request for approval for 7192449, 7192744: fix up tests to accommodate jtreg spec change

[Dmeetry Degrave]

Hi,

We have a number of tests failed with a new version of jtreg. These 
fixes care about some of them in langtools, we need them fixed in jdk7u 
as well. These is a straightforward back port.
