There is classloading issue in one option of obtaining passwords from external commands. External passwords for vault are introduced by RFE: https://issues.jboss.org/browse/EAP6-221 When vault is configured to use external password obtained from CLASS, e.g. : <vault-option name="KEYSTORE_PASSWORD" value="{CLASS}org.jboss.security.plugins.TmpFilePassword:${java.io.tmpdir}/tmp.password"/> JBoss EAP 6.4.0.DR2 is unable to start, because of ClassNotFoundException.
Verified in EAP 6.4.0.DR10
