There is a weeks-long process separating when a change gets pushed into 
a JDK 7 integration workspace, like TL, and when the promoted bits are 
available for download.  The closer a changeset gets to the master, the 
most tests should be run against it.

An individual developer should not be expected to run all the tests, but 
if at least the regression tests in the code base are not all run on 
multiple platform by the time the change hits the master, I'd argue 
there is a process problem.  Of course, it is also a problem if the 
tests are run and the results aren't examined adequately.
