How to setup Subversion to use the command-line client
It might happen that the JavaHL library used by NetBeans Subversion support doesn't work properly or, even worse, it causes the JVM to crash. The fallback solution in such a case is to setup NetBeans to use the command line client exclusively.
You can do that by setting the switch
-J-DsvnClientAdapterFactory=commandline
from the command-line or in the netbeans.conf file.
