----------------------------------

Hi Jukka, 

I just tested the latest commits, and it's looking quite good. I only saw 2 tests that don't
seem to work yet, but I'm assuming you're already aware of this ? 

EquiJoinConditionTest

	testInnerJoin1(org.apache.jackrabbit.test.api.query.qom.EquiJoinConditionTest)	0.692
	testInnerJoin2(org.apache.jackrabbit.test.api.query.qom.EquiJoinConditionTest)	0.608
	testRightOuterJoin1(org.apache.jackrabbit.test.api.query.qom.EquiJoinConditionTest) + [ Detail
]	0.138
|/testroot/node1| is not part of the result set	
	testRightOuterJoin2(org.apache.jackrabbit.test.api.query.qom.EquiJoinConditionTest)	0.09
	testLeftOuterJoin1(org.apache.jackrabbit.test.api.query.qom.EquiJoinConditionTest)	0.103
	testLeftOuterJoin2(org.apache.jackrabbit.test.api.query.qom.EquiJoinConditionTest) + [ Detail
]	0.071
/testroot/node1|| is not part of the result set	

Best regards,
  Serge Huber.

much any non-trivial data set.
