Seems like an argument that this function is in the wrong location.
I think CharBuffer.toString() is actually quite obscure. I note that most of the
Buffer classes have toString() methods that report the *status* of the buffer, e.g.
java.nio.HeapByteBuffer[pos=0 lim=1000 cap=1000]
Compared to other Buffers' toString() methods, CharBuffer is the outlier: its
toString() produces only the contents of the CharBuffer without any
meta-information. This is rather surprising.
