SFTP withing jedit doesn't work in OpenIndiana

I use a lot the FTP plugin from jEdit.
This plugin allows you to open a SFTP connection to a remote host via ssh and
work with files from the remote host, as if they are local. The plugin is
available via the file browser.

You can load and save the files.

Within OpenIndiana this just doesn't work anymore.
The activity.log shows:

The verification fails. I had written to the OpenIndiana Mailinglist and 
the successful suggestion from Onno Molenkamp was, to remove the 
sun.security.pkcs11.SunPKCS11 provider from /usr/jdk/latest/jre/lib/security/java.security

After removing and renumbering the providers there, the SFTP Plugin works again in OpenIndiana.
