Description

Presume this is on the TODO list :)

I'd like to use

@JavaClass("java.nio.ByteBuffer")
open class JavaNIOByteBuffer: JavaNIOBuffer {
...
  @JavaMethod
  open func get(_ arg0: [Int8], _ arg1: Int32, _ arg2: Int32) -> JavaNIOByteBuffer!
...
}

but the projection of byte[] is not inout.

Research direction

Start by tracing how JavaKit projects Java primitive arrays, especially byte[], into Swift method parameters. Compare that behavior with the requested inout projection in the JavaNIOByteBuffer example; done when the example can use the projected byte array as inout.
