Hello,

I'm getting the following exception when I try to update job settings, when the
Subversion plugin is used:

javax.servlet.ServletException: java.lang.NullPointerException

When I remove the subversion plugin, everything works fine.

I'm using:

• Hudson V 1.333
• Hudson Subversion Plug-in V 1.7
• JBoss 4.2.3 GA
• java version "1.6.0_06"
  Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
• Ubuntu 8.04 server
