Crimson (the version issued with JDK 1.4) crashes as follows:

java.lang.InternalError: fillbuf

Exception in thread "main" 

Last few SAX events reported were:

ContentEmitter#startElement ,code,code at line 11201
characters (2)
characters (1)
End element code
characters (71)
ContentEmitter#startElement ,code,code at line 11202

The contents of the XML around this line were:

11200: <p>If the text node contains the sequence of characters
11201: <code>]]&gt;</code>, then the currently open CDATA section should be
11202: closed following the <code>]]</code> and a new CDATA section opened
11203: before the <code>&gt;</code>.</p>

This has parsed successfully in the past; the changes made to the file before 
the failure were in an unrelated part of the document. So I guess there's some 
buffer boundary condition that's been hit, perhaps the "]]" spanning the end of 
a bufferful of data while the parser was checking for "]]>".

Adding some dummy text before the paragraph above fixed the problem.
