Yup, it's a known issue - ESB-827 and ESB-853 it's because 18.104.22.168 ships with Mina 2.0 M6 for gshell and 1.1.7 as a bundle, however the mina bundle doesn't specify an upper threshold for import-package so gets a bunch of classes from Mina 2.0, causing all sorts of issues.
There's a workaround given in the second issue, follow the link, basically you can just rebuild the mina 1.1.7 bundle and install it to work around the issue.
Otherwise you can find previous versions of our installers here by version, each subdirectory has the binary installer (windows/UNIX) and the accompanying source.
Thanks for the information. I was able to successfully rebuild the mina library. My question now becomes, where exactly do I install this new jar file and should I remove the pre-existing mina 2.0.0 stuff?
You want to do osgi/list | grep Mina and then do osgi/uninstall on the bundle ID, then do:
to install the bundle you've built. After that you should be able to install camel-mina alright.
