I'm running into a startup problem using Tomcat 8 and Java 8 during annotation scanning.
I get many error messages similar to these two: Jun 30, 2014 12:44:26 PM org.apache.catalina.startup.ContextConfig processAnnotationsWebResource SEVERE: Unable to process web resource

java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) I tried disabling annotation scanning by putting metadata-complete="true" in web.xml, but scanning is still being done. I suspect part of that is because the application is using WebSockets, so Tomcat really does need to scan for annotations like java.websocket.server.ServerEndpoint. I'm using Tomcat 8.0.9. I saw the same problem in 8.0.8 as well, but the error is NOT in 8.0.5. The Java version is 1.8.0_05 (64-bit linux build) Any help much appreciated.
