A DESCRIPTION OF THE PROBLEM :
I get a java.lang.NullPointerException when parsing a large xml document. The parsing is done with javax.xml.parsers.DocumentBuilder.parse(). The original document was about 2.5 MB, but was able to get it to fail with documents as small as about 390 KB.

This problem is new to 5.0. I can compile the test program I have included with jdk 1.4.2_04, and it successfully parses the xml document from the file.

This problem does not occur with all large xml documents. I will provide a sample document that will cause the failure.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run provided XMLParseTest code. Give the filename of the xml file as a parameter to the test program. Make sure the dtd file is located in the same directory as the xml file.

Get the xml and dtd files from:

ftp://ftp.avamar.com/pub/files/sun/x6.xml
ftp://ftp.avamar.com/pub/files/sun/event_catalog.dtd

Here are the MD5 checksums for these files:

5cb8504288d0de0f66cdc2d62d7c3c85 x6.xml
04fc7179546f9a624a771803ed131905 event_catalog.dtd



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The test program produces no output if it doesn't get an exception calling parse().
ACTUAL -
java.lang.NullPointerException
