Hi, We have new failure on OST from patches merged to master yesterday, the failure started after the merge of [1], but as there were quite a few patches merged quickly I can't make sure it is the one causing it(OST aren't ran per-patch). The test that fails is [2] when attempting to start the VM. The error from the API side: RequestError: status: 500 reason: Internal Server Error detail: javax.ejb.EJBException: java.lang.NullPointerException at org.jboss.as.ejb3.tx.CMTTxInterceptor.handleExceptionInNoTx(CMTTxInterceptor.java:213) at org.jboss.as.ejb3.tx.CMTTxInterceptor.invokeInNoTx(CMTTxInterceptor.java:265) at org.jboss.as.ejb3.tx.CMTTxInterceptor.supports(CMTTxInterceptor.java:374) at org.jboss.as.ejb3.tx.CMTTxInterceptor.processInvocation(CMTTxInterceptor.java:243) at org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:340) ....
