unable to batch create then save 100000 nodes under the root node; it works with 10000
--------------------------------------------------------------------------------------

                 Key: JCR-588
                 URL: http://issues.apache.org/jira/browse/JCR-588
             Project: Jackrabbit
          Issue Type: Bug
    Affects Versions: 1.0.1
         Environment: Tested both on Linux (Debian testing + sun jdk 1.5) and Windows XP +sun
jdk 1.5 both with -Xmx300m
It fails identical on both.
            Reporter: Cristian Grozea


When using the JackRabbit with the simplest setup, as described in the "FirstHops", the following
code succeeds when the number of node to be created is 10000, but not when it is 100000.
---------------------
Code:

			for (i = 0; i < 100000; i++) {
					Node hello = root.addNode("gct" + i);
					// Node world = hello.addNode("world");
					hello.setProperty("message", "gctHello, World!" + i);
					System.out.println(i);
				}
				session.save();
