Hi Michael,
The JVM used by Tamino to execute SXS has restrictions to prevent falseful usage and harm the Tamino server. Exchanging the classloader and the security is among these restrictions.
Class org/xml/sax/XMLFilter of Your XALAN/SAXON implementation obviously violates these restrictions.
Please use the common SAG methods to contact the Tamino support on the issue.
Best regards, Michael K
