For conj-742, Squirrel Client reports " Client does not support authentication protocol requested by server. plugin type was = 'xxx' "
This problem was fixed in commit 4e0705b.
But after this commit changed the loader into static, it reports Access denied problem (stack as at bottom). And this problem as been reported on conj-807.
I've tested that for conj-742, there is only need to specify the class loader Driver.class.getClassLoader() to solve the Squirrel Client problem. So I proposed this fix to solve both conj-742 and conj-807.
