Awt thread is blocked by Hints thread. AnnotationHolder calls BaseDocument.render() which is slow down by java.security.AccessController, maybe because of many new threads in DocumentViewOp

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
