Description
These two tests are failing in jdk7u/jdk7u-dev at this time, possibly because JDK-7183753 was back-ported to jdk7u without the hotspot changes.

Here is an example failure:

Comments
Initially Hotspot changes in src/share/vm/services/diagnosticCommand.hpp were integrated to hs24 b16 via 7178703. This fix caused these two tests to fail as the output changed, and the issue was addressed by 7183753. The problem appeared in jdk7u/jdk7u-dev once again because 7183753 was integrated to 7u10 and 7178703 wasn't. Finally, Hotspot changes are on their way to 7u12 by 8002661/8002662.
