Cannot start version 2.1.4 because of UnsupportedClassVersionError

[portig]

I managed to deploy this version of sventon by copying svn.war into
the webapps subdirectory in my Tomcat 6.0.20 installation on an iMac
running Leopard 10.5.8. When I try to start the app by means of the
Tomcat manager screen sventon fails to start with the message
"Application at context path /svn could not be started". The
resulting sventon log file ends up showing a stack trace as follows:

Previously I had been running sventon 2.0.5 without problem. I
followed the upgrade instructions for sventon calling for the deletion
of several items in the Tomcat tree.

Where should I look to solve this issue. Googling for other people
having this problems has not been successful.

Thanks . . .

Sounds like you need to upgrade your JVM...1.6 should do it.

Hi!

According to the SVNKit mailing list, the SVNKit JAR file was
accidentally compiled using JDK 1.6.

To be able to run sventon on JDK 1.5, simply replace the SVNKit
library by replacing the file lib/svnkit-1.3.1.jar with the one found
here: http://maven.svnkit.com/maven2/org/tmatesoft/svnkit/svnkit/1.3.1/

Regards
Jesper

Thanks for the suggestion, however I cannot do the upgrade to 1.6
because I am running on a pre-Intel Mac.

This indeed solved the problem.

Thanks for the suggestion, Harald
