Stagemonitor no longer works under Wildfly 10 (SNAPSHOT)

See original GitHub issue

While investigating issue #189 I came across the following error when starting stagemonitor under Wildfly 10:

It seems to be related to a new version of bytebuddy as reverting to bytebuddy 1.4.7 (as in version 0.27.2) fixes the problem.

Element	Version
Stagemonitor	0.28.0-SNAPSHOT

@raphw I tried Byte Buddy 1.4.21 and everything seems OK under Wildfly 10. I will open a PR to fix this in the next StageMonitor release. Thank you!
