Hi:

> ConsoleUtil.writeInfo("type %s size %s "%(type(-2147483648), sys.maxsize)) 
> INFO: type <type 'long'> size 2147483647

Sorry, but we couldn't care less about the python type().
What matters is the Java type that Jython passes to the setValue() Java code:

> value = -2147483648
> print(value.__class__.__name__)

.. and the Java type of the PV data:

> print(pvs[0].getValue().__class__.__name__)

Knowing the PV type and the actual data type passed in it'd be easier to figure out how the value is handled.
For example, it's possible that Jython is passing a java.lang.Long, but the PV type maps to a VShort and the value is thus truncated.

Thanks,
Kay
