Thanks for all your work here.  Yes, my java version is 6.  We need to 
support java 7 in Grouper 2.1.4+...

https://bugs.internet2.edu/jira/browse/GRP-878

I think it is a lot more urgent to keep java version on desktops up to date 
than servers, but I do agree that we need to support the Java version that is 
supported by Oracle...

Thanks,
Chris

Hi,

Thanks for your reply:

- Which version of Java did you use?

I made some further test sessions and it is now clear that, in my 
context, the varying error reports only occur with Java 7. I tried many 
combinations of java version (1.6.0_33, 1.6.0_38, 1.7.0_05, 1.7.0_11), 
oracle or hsql database, with hibernate.cache.use_query_cache set to 
true or false: errors never occurred with Java 6, and often with Java 7. 
(You'll find in annexe yet another example of reported errors).

- Has anybody else noticed this (test suite reporting errors with java 7)?

OK. But this is unfortunate: in my opinion unit tests should be 
deterministic, i.e. reported errors should not vary from one run to 
another in the same context, and certainly not differ if a test is run 
in a suite or individually.
If running individual tests becomes necessary to establish if errors 
reported by "-test -all" are to be taken seriously or not, it should be 
described in the installation documents (e.g. README.txt) when and how 
to run them.

I was using Java 7 because it has been available since July 2011 and 
Java 6 won't be supported after February 2013 (after two extensions, the 
original EOL was July  2012), and I did not find any information against 
it in the documentation or the Grouper user mailing list.

Maybe the requirement document should also state what is the most recent 
version of Java that has been used successfully by the developers. (cf
