Eclipse 3.1RC1 problem on Fedora FC3

I'm trying to get subclipse work on Ecliplse 3.1RC1, but
when I open the prefereces in Eclipse and go to Team->SVN
I get the dialog saying:

Unable to create the selected preference page
Plug-in org.tigris.subversion.subclipse.ui was unable to load class
org.tigris.subversion.subclipse.ui.preferences.SVNPreferencesPage.

I have installed subversion 1.2.0 and I have compiled
libsvnjavahl-1.so.0.0.0 and placed it in /usr/java/jdk1.5.0/jre/lib/i386/

The svn-javahl.jar file is placed in /usr/java/jdk1.5.0/jre/lib/ext/

The unit tests for the svn-javahl.jar works OK, and so does the
svn command line program (svn)

I have installed the latest subclipse plugin by using the update URL:
http://subclipse.tigris.org/update and when I look at the plugins tab
in eclipse it seams that org.tigris.subversion.subclipse(0.9.31) is
installed.

Any suggestions?
