FULL PRODUCT VERSION :
java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0
Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
During a routine parse, the javax.swing.text.html.parser.Parser enters an infinite recursion loop resulting in a StackOverflowError. The apparent source of the problem is the following method in this class:

[code]

boolean legalElementContext(Element elem) throws ChangedCharSetException {

// System.out.println("-- legalContext -- " + elem);

// Deal with the empty stack
if (stack == null) {
// System.out.println("-- stack is empty");
if (elem != dtd.html) {
// System.out.println("-- pushing html");
startTag(makeTag(dtd.html, true));
return legalElementContext(elem); // <--- Infinite Recursion Here
}
     return true;
}

[/code]

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Successful parse
ACTUAL -
Infinite recursion loop, resulting in total JVM crash
