Most likely the problem with Bytes.toString(byte[]) is caused by #1002, since Bytes.toInt(byte[]), Bytes.toHex(byte[]), etc, works:

>>> import array
>>> qualifier = array.array('b', [98, 121, 116, 101, 45, 115, 105, 122, 101])
>>> qualifier
array('b', [98, 121, 116, 101, 45, 115, 105, 122, 101])
>>> Bytes.toHex(qualifier)
u'627974652d73697a65'

which we can verify

>>> [hex(b) for b in qualifier]
['0x62', '0x79', '0x74', '0x65', '0x2d', '0x73', '0x69', '0x7a', '0x65']

Workaround for now:

>>> qualifier.tostring() # note case!
'byte-size'

re choice of the overloading for Bytes.toBytes(java.lang.String) vs Bytes.toBytes(char), I don't think this works if both overloads are available. Perhaps we should make that possible, but that seems like a possible breaking change. So the docs on the wiki should be updated.

However, you can control the specific overloaded method that is selected like so:

>>> from java.lang import Short
>>> Bytes.toBytes(Short(ord("v")))
array('b', [0, 118])

You could also do this, but in this specific library there is no overloading for Character. Nor is there an implicit conversion to short in Jython, although that would be problematic given that char is unsigned and short is signed.

>>> from java.lang import Character
>>> Bytes.toBytes(Character("v"))
