Code review: 7126979 (props) JCK test java_lang/System/GetProperties.java failing [macosx]

[Michael McMahon]

Could I get the following change for jdk7u-osx reviewed please?

http://cr.openjdk.java.net/~michaelm/7126979/webrev.1/

The freeProps() call added by mac port can only be called once. Issue 
seen if System.setProperties(null) is called.
GetJavaProperties() called a second time, which is supposed to return 
the statically populated information
from first call. But some of it has been freed already.

Fix is to remove the freeProps() code added in the original port 
changeset. The fix reverts the mac specific code
to the original version.
