Currently, in order to fully support all the forms a Python iterator can take, jpyinterpreter generates the following code for FOR_ITER:
try { do { TOS' = next(TOS) // code in for block } while(true); } catch (StopIteration e) { // code after for block }
This is highly atypical in Java, and the JVM probably would have a harder time optimizing its standard for iterator loop:
while (TOS.hasNext()) { TOS' = TOS.next(); // code in for block } // code after for block
We can look at TOS to see if it a known iterator type (i.e. PythonIterator), and if so, generate the more typical Java loop.
