Hangup using the "continue-after-fatal-error" feature

[Stanimir Stamenkov]

Although I'm aware the behavior while using this feature is undetermined I report such bugs because of others which may are interested in improving the reliability while using the feature.

<?xml version="1.0" encoding="US-ASCII" ?>
<!DOCTYPE foo SYSTEM "foo.dtd">
<foo bar="

  />

I'm attaching a sample code and input data which cause the parser (Xerces-J 2.9.1) to hang.
