Calling .to_java(Java::byte[]) on a RubyArray doesn't convert to a multi-dimensional byte array, but fails with a TypeError exception

Am I doing something wrong here or should this be supported?

>> ["foo".to_java_bytes].to_java(Java::byte[])
TypeError: wrong argument type #<Class:0x32632915> (expected Array)

In order to achieve this, I needed to do the following intend:

>> outer = Java::byte[10,0].new
=> [B[[B@78dc256, [B@6bd19ff9, [B@f5dcbbc, [B@56eaab85, [B@48a2d557, [B@3a646802, [B@15e87941, [B@5170a5a3, [B@3a8a9a1a, [B@618b3efc]@7cd4446b
>> foo_bytes = "foo".to_java_bytes
=> byte[102, 111, 111]@54b5360e
>> outer[0] = Java::byte[foo_bytes.size].new
=> byte[0, 0, 0]@417e7d7d
>> outer[0] = foo_bytes
=> byte[102, 111, 111]@54b5360e

This variant doesn't seem to work either.

>> ["foo".to_java_bytes].to_java(Java::byte[].java_class)

multi-dimensional arrays have been converting fine for a while but still cases such as a Ruby array with a nested Java array where not handled ... but this should now be working as well (since 1.7.20), thank you!
