Hi Niko!

Thanks to Carl Friedrich, I found that the problem with that test is 
that you must to annotate it explicitly with r_ulonglong, else the 
annotation degenerates to SomeObject and the rtyper assign it the 
PyObject* type.

I checked in the test in 
oosupport.test_template.operations.test_compare_big_ullongs; now the 
test passes in gencli but fails in genjvm with the same error as the 
full translation. Moreover, I also addedd a new failing test to 
oosupport.test_template.runtest.test_big_ullong.

I don't know if I will find the time to look at them today, though.
