A DESCRIPTION OF THE PROBLEM :
JEP 268 Promised replacement of the old internal catalog resolver, JEP proposes to remove the internal catalog resolver implementation after the public API is delivered. But new implementation doesn't support TR 9401 which makes it impossible to use it for example in the XJC

Related issue: https://github.com/eclipse-ee4j/jaxb-ri/issues/1171



REGRESSION : Last worked in version 8

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Use javax.xml.catalog.CatalogManager with OASIS TR9401 simple entity catalog format

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
1. No exception thrown(there shouldn't be one even when catalog resolver cant parse the syntax see spec https://www.oasis-open.org/committees/download.php/14809/xml-catalogs.html#s.res.fail )
2. Catalog entries are used for resolving
ACTUAL -
javax.xml.catalog.CatalogException: JAXP09030002: Failed to parse the catalog file.

CUSTOMER SUBMITTED WORKAROUND :
Using old internal com.sun.org.apache.xml.internal.resolver.Catalog
