[jdom-interest] RE: Memory and Speed problems with SAXBuilder

The beta 8 problem was not limited to JDK 1.4.1. I know it happened on
JDK 1.2.2 also, and I thought it happened on JDK 1.4.0 as well, but I'm
not positive.

You are probably using JDOM beta8 with JDK 1.4.1. These two are
due to the memory leak bug in StringBuffer introduced in JDK 1.4.1.
For more information, please see 

Sun does not plan to fix this bug until JDK 1.5 (Tiger).

To fix this problem, you have 2 solutions:
  1. Stick to JDOM beta8 but downgrade to JDK 1.4.0 or 1.3.1
  2. Stick to JDK 1.4.1 and upgrade to the latest JDOM which includes a

workaround for the JDK bug.
