Subject svn commit: r1539990 - in /jackrabbit/oak/trunk: oak-core/src/main/java/org/apache/jackrabbit/oak/query/ oak-jcr/src/test/java/org/apache/jackrabbit/oak/jcr/query/

New Revision: 1539990

URL: http://svn.apache.org/r1539990
Log:
OAK-1155 PropertyIndex cost calculation is faulty
 - pushed the traversal fallback flag to the query, this allows for the distinction between
the defined query indexes and the traversal one which should neved be picked if there's a
valid query index available
