FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)


FULL OPERATING SYSTEM VERSION :
glibc-2.1.3-22.1
kernel 2.2.20
Red Hat Linux release 6.2 (Piglet)
VA Linux Release 6.2.4 02/21/01


A DESCRIPTION OF THE PROBLEM :
I am using URIs that look like this:

    tag:quiq.com,2002:enumeration.dtd

This is a perfectly good URI, and it's absolute. However,
the Crimson parser thinks that it is a relative URI, and
prepends the current path to it as if it was a file name.

The offending method is resolveURI(String uri), line 2741 of
org/apache/crimson/parser/Parser2.java in the standard 1.4
distribution for Linux. The if statement on line 2753 fails in
the case where there is a colon but no slash: it treats this
as if the slash preceded the colon. But a colon and no
slash means the same thing as a colon preceding a slash:
it is an absolute URI.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Read the code I outlined.
2. Think.
3. Go look at the URI spec: http://www.ietf.org/rfc/rfc2396.txt

This bug can be reproduced always.

CUSTOMER WORKAROUND :
Use Xerces instead of Crimson.
