When I call a function which take byte[] as its argument (for example javax.sound.midi.SysexMessage# setMessage(int status, byte[] data, int length)) >>> import javax.sound.midi.SysexMessage as S >>> s = S() >>> s.setMessage(0xF0, [0x7E, 0xFF, 0x09, 0x01, 0xF7], 5) it throws an error. TypeError: setMessage(): 2nd arg can't be coerced to byte[] This code works well on jython2.1.

Did you submit this as deferred for a reason? It seems like something we should get for the 2.2 release to me.

Sorry, I misundersttod the word 'deffered' like 'defect'.

Ahh, gotcha. I'm moving this to be fixed for beta2 then.

This is failing because 0xFF and 0xF7 are both greater than 127, the largest value you can store in a byte in Java. As such, I'm not sure this is actually a bug even though it's different than jython2.1. I think it's better to only allow Java bytes, values from -128 to 127, rather than doing the more Pythonic thing and making bytes from 0-255 since we're converting to a Java type.
