Elliotte Rusty Harold commented on XERCESJ-456:
-----------------------------------------------
org.apache.xerces.impl.dtd.AbstractDTDGrammar appears to no longer exist, but I
do see code like this in DTDGrammar:
{noformat}
} else {
throw new RuntimeException("Unknown content type for a element decl
"
+ "in getElementContentModelValidator() in
AbstractDTDGrammar class");
}
{noformat}
Even if an exception is OK here, it shouldn't be a raw RuntimeException but
something more specific.
