If you set the override to true in the method object (using AccessibleObject.setAccessible) you will be able to invoke the method. This works in the JRE 8 xsl transformer. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@xalan.apache.org For additional commands, e-mail: dev-h...@xalan.apache.org
