The ide log file

Every time NB starts I find this message in the ide log file:
---

Looks like some kind of a conflict between the HTML functionality and the JBoss plugin - although I can not reproduce on my machine. Petr and Marek, can you please investigate?

Report from old NetBeans version. Due to code changes since it was reported likely not reproducible now. Feel free to reopen if happens in 8.0.2 or 8.1.
