The following tests that were recently enabled fail with jdk17 :

 org.jboss.as.test.clustering.cluster.ejb.forwarding.NonTxClientEJBForwardingTestCase org.jboss.as.test.clustering.cluster.ejb.forwarding.NonTxRemoteEJBForwardingTestCase org.jboss.as.test.clustering.cluster.ejb.forwarding.TxClientEJBForwardingTestCase org.jboss.as.test.clustering.cluster.ejb.forwarding.TxRemoteEJBForwardingTestCase

The JDK17 failure is due to the legacy security based setup task: https://github.com/jbossas/jboss-eap7/blob/792bf2ea1b2141df78d2003574e788b7f12b11d9/testsuite/integration/clustering/src/test/java/org/jboss/as/test/clustering/cluster/ejb/forwarding/AbstractRemoteEJBForwardingTestCase.java#L253

Also AuditLogBootingSyslogTestCase fails with oracle 1.8_371 and ibm jdk
