Hi,
a Java module parsing an SVG file suddenly throws an exception, the
error can be traced back to the following:
Retrieving http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd
with a user-agent containing the string 'java' results in a 500 server
error, any other user-agent works fine (see traces below).
This breaks the Apache Xerces parser, which tries to load the DTD
using the user-agent string 'Java/1.6.0_20'.
Is this intended behavior or a temporary server error?
