]
Michael Glavassevich updated XERCESJ-1260:
------------------------------------------
Description:
If a DTDGrammar is pre-parsed and stored in an XMLGrammarPool which is shared
across parsers running in different threads, it's possible that the content
model builder will fail with one of the exceptions below. The
createChildModel() needs to be synchronized (like the analagous method in
CMBuilder for SchemaGrammars).
