I've just installed Subclipse SVN plugin version 1.8.x. but as always there ware problems. This time it was JavaHL library. Default instalation from openCollabNet is 1.6.7 which isn't compatible with this version of Subclipse:
Subclipse Version SVN/JavaHL Version
1.8.x 1.7.x
1.6.x 1.6.x
1.4.x 1.5.x
One option would be to revert to previous version which I didn't quite like.
Second is "unrecommended" installation from MacPorts.
Instalation goes ok but with few tweeks! Just run the following command(s) and you are set to go!
sudo port install subversion-javahlbindings
If you have problems with updating from previous version:
sudo port clean subversion-javahlbindings
sudo port selfupdate
sudo port upgrade outdated
If you have problems with updating db64:
sudo port clean -f --all db46
sudo port selfupdate
sudo port install db46
