Code in o.n.m.web.beans.navigation.actions.WebBeansActionHelper.hasJsr330()
leads to opening a child FileObject in EDT. The file is locked by thread
"org.netbeans.modules.java.hints.declarative.DeclarativeHintRegistry" for a
long time, probably because the filesystem is busy.

Reassigning to javaee/CDI. Please evaluate. If it's difficult to fix the bug, I
think this issue can be closed as WONTFIX, as it is mainly caused by slow
filesystem. Thank you.
