issue with kvmsg get/set operation

[ThomasCraigNelson]

Note the following test
@test
public void showKmsgIssueTest()
{
kvmsg msg = new kvmsg(0);
msg.setKey("mykey");
kvmsg clone = msg.dup();
clone.setKey(clone.getKey() + "theirkey");
// This should pass but does not in 0.5.3:
assert(clone.getKey().equals("mykeytheirkey"));
}
However with the following change in kvmsg it passes:
// Set message getKey as provided
public void setKey(String key)
{
byte[] msg = new byte[key.length()];
System.arraycopy(key.getBytes(ZMQ.CHARSET), 0, msg, 0, key.length());
frame[FRAME_KEY] = msg;
present[FRAME_KEY] = true;
this.key = null;// THIS LINE FIXES the test. Used in later getKey optimization....
}
