[jboss-jira] [JBoss JIRA] (WFLY-2692) infinite wait in BasicComponent#waitForComponentStart() causes server hang

infinite wait in BasicComponent#waitForComponentStart() causes server hang -------------------------------------------------------------------------- Key: WFLY-2692 URL: https://issues.jboss.org/browse/WFLY-2692 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: EE Affects Versions: 8.0.0.CR1 Reporter: Thomas Frühbeck Assignee: David Lloyd Labels: EE, MSC, hangs Attachments: WFLY-2692_infiniteHang_stacktrace.log some error in deployment may cause infinite wait on BasicComponent#waitForComponentStart(): protected void waitForComponentStart() { if (!gate) { // Block until successful start synchronized (this) { while (!gate) { // TODO: check for failure condition try { wait(); The server life cycle management is completely blocked, no normal redeployment/shutdown will work! Please provide some remedy (e.g. timed wait and fail?), IMHO this is really _very_ distressing for a production ready system.
