Michael Glavassevich updated XERCESJ-1516:
------------------------------------------
Description:
An XSDTypeAlternativeTraverser is always created by the XSDHandler, regardless
of whether we're doing XML Schema 1.1 processing. This causes us to load
Eclipse PsychoPath even when it's not going to be used. By only creating an
XSDTypeAlternativeTraverser in XML Schema 1.1 mode we can avoid loading
PsychoPath classes in XML Schema 1.0 mode.
This should allow people to continue using Xerces without having to include
PsychoPath on their class path. With Xerces-J 2.11.0 they would get the
following stack trace without the jar:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/eclipse/wst/xml/xpath2/processor/XPathParserException
at org.apache.xerces.impl.xs.traversers.XSDHandler.createTraversers(Unknown

at org.apache.xerces.impl.xs.traversers.XSDHandler.prepareForTraverse(Unknown
