Hi everyone,

> Fiji is still shipped with Java 6 to support some old Mac OS releases

That is true, and there are other reasons too. See also this FAQ entry:
http://imagej.net/Frequently_Asked_Questions#Why_does_ImageJ_still_target_Java_6.3F

A lot of effort [1] actually went into making sure that things like "import
os" _do_ work (including with the current Jython 2.5.3). So please let us
know the details of the failure if it is still not working for you with a
fully up-to-date ImageJ.
