issues mocking method with byte[] as argument

I cannot seem to verify method with following signature:

public void write(File file, byte[] bytes)

I'm doing:

1 * collector.cachingFileWriter.write(new File(temp.dir, "FooTest.stderr.bin"), 
"out".bytes)

it fails with:

I worked around by changing the interface to take String instead of bytes
