[Exist-open] New JUnit tests - intersection of ResourceSet - how to debug eXist with JUnit and jdb

[Jean-Marc V. <jm...@fr...>]

I have commited a new JUnit test (that triggers the error mentioned 
yesterday
    in  org.exist.xpath.FunPosition.eval() ) :
- org.exist.xmldb.test.ResourceSetTest

It tests 2 new classes in org.exist.xmldb :
- MapResourceSet.java
- ResourceSetHelper.java
The latter does an intersection of 2 ResourceSet and makes use of the 
former.

I also added more tests in :
- CreateCollectionsTest.java
- ResourceTest.java   ( given by Kevin O'Neill on Mon, 2003-03-31 at 14:13 )

I also commited this small helper for debugging based on bin/run.sh :
bin/jdb.sh

Below is sample session with bin/jdb.sh . We debug the new 
ResourceSetTest (that reveals the FunPosition bug ) run by JUnit .

Notes:
- user commands in jdb are preceded by > or main[1]
- the "catch all" command is essential  otherwise  JUnit catches itself 
all Exceptions (normal, JUnit has to run all tests whatever happens)
- I didn't solve the problem -:((
