How to reproduce the bug:
-------------------------

 - Compile StopWatch.java and XmlTest.java in your test directory.
 - Copy dummy.xml and dummy.xsl to your test directory.
 - Create empty heaps, logs, tmp directories in your test directory.
 - Run XmlTest as follows:

java -XX:HeapDumpPath=./heaps/$$_dump.hprof -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Xloggc:logs/$$_gc.log -XX:ParallelGCThreads=4 -XX:+HeapDumpOnOutOfMemoryError XmlTest

You'll get following output:

java.lang.OutOfMemoryError: Java heap space
Dumping heap to ./heaps/$$_dump.hprof ...
Exception in thread "pool-1-thread-5" java.lang.OutOfMemoryError: Java heap space
