RFR: JDK-8150704 XALAN: ERROR: 'No more DTM IDs are available' when transforming with lots of temporary result trees

[Langer, Christoph]

Hi,

I've created a fix proposal for the issue I have reported in this bug:
https://bugs.openjdk.java.net/browse/JDK-8150704

The webrev can be found here:
http://cr.openjdk.java.net/~clanger/webrevs/8150704.1/

The Xalan parser would eventually run out of DTM IDs if xsl transformations involve lots of temporary result trees. Those are never released although they could. A testcase is included for this. I've also done some cleanups in the Xalan code and in the tests.

Thanks in advance for looking at this :)

Best regards
Christoph
