I don't really know if it's a valid query. I should search for every label that
has a property value (what ever name the property may have) that is somewhere
under a specific "mycoreclass" node. Either way Jackrabbit should of cause not
exit with a NullPointerExeption here.
I'm using the very current svn snapshot of jackrabbit. For the records line
550-557 of LuceneQueryBuilder.java look like this now:
String field = "";
try {
field = node.getProperty().toJCRName(nsMappings);
} catch (NoPrefixDeclaredException e) {
// should never happen
exceptions.add(e);
}
