I have an EAR file with several "@Singleton @Startup" beans. Each bean having a number of @Inject and @Resource fields. When I deploy the EAR in WildFly 11 it sometimes fails with a NoSuchElementException (see log.txt for a full stacktrace).
I cannot reproduce it consistently but it seems to only happen on a "clean" WildFly installation. I haven't seen this on earlier versions of WildFly.
Let me know if you want me to try to build an EAR for reproducing this.
