Why JBoss is not able to parse some TLD files ?

Issue

• Getting the following exception while loading TLD files :

Caused by: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS018014: 
It is not possible to syntactically analyse the descriptor "/C:/abc/xyz/JBOSS/jboss-eap-6.1/bin/content/test.war/WEB-INF/tlds/mytld.tld" en [5,5]
