NB 5.5 dev 200605040500
OS Fedora Core 2

I was getting through test specs when I found this bug.
When trying to open XML file in an EJB project the NB gets frozen and the CPU
gets high load.

Steps to reproduce:
==========================================================
A) add glassfish to netbeans
  1) press Ctrl+5
  2) right click on servers and select "Add server..." from the menu
  3) change string in field name to "GlassFish Application Server"
  4) press "Next"
  5) through button "Browse" point to a directory with glassfish installed
  6) press "Finish"
B) create new EJB project
  7) press Ctrl+Shift+N
  8) from category "Enterprise" select "EJB module" and press "Next"
  9) make sure "GlassFish Application Server" is selected and press "Finish"
C) create new Persistance file
  10) press Ctrl+N
  11) select "Persistence" -> "Entity Class"
  12) type "test" to package field
  13) ignore warning about missing persistance unit and press "Finish"
    Status: string "@Entity" should be underlined in red color in line 22
  14) click on the underlined string "@Entity" and press Alt+Enter
  15) accept an offer to create persistance unit and press "OK"
D) try to open newly created XML file
  16) from project tree view try from folder "Configuration Files" doubleclick
on persistence.XML
    Result: the IDE is frozen and CPU load gets to 100%
