Implemented a temporary Infinispan compatibility workaround to pause related tests for Java 23+ using @MaximumJavaLevel(javaLevel = 22), with a TODO to remove once compatibility is resolved. Added an appClientSupport integration test in Open Liberty, configuring InstantOn and validating remote EJB injection via java:global lookup to ensure proper integration. These changes reduce risk in CI and increase confidence in deployment readiness.
