Looking at the current code, "new String()" call still remains in WsFrame.java
Starting with Line 270:
if (controlBufferBinary.remaining() > 0) {
CoderResult cr = utf8DecoderControl.decode(
controlBufferBinary, controlBufferText, true);
if (cr.isError()) {
controlBufferBinary.clear();
controlBufferText.clear();
throw new WsIOException(new CloseReason(
CloseCodes.PROTOCOL_ERROR,
sm.getString("wsFrame.invalidUtf8Close")));
}
reason = new String(controlBufferBinary.array(),
controlBufferBinary.arrayOffset() +
controlBufferBinary.position(),
controlBufferBinary.remaining(), "UTF8");
}
Why use "new String(.., UTF8)" when there is
"utf8DecoderControl.decode(..)" call several lines above?
Isn't it supposed to use controlBufferText here ?
