I have tomcat 7.0.53 and have been having a problem with the following
error when sending a binary message "CloseReason: code [1002], reason
[The client frame set the reserved bits to [x] which was not supported
by this endpoint]" where x is between 1-7 when printed out. So I
remote debugged and stepped through the WsFrameBase.class source code.
This source code is what sets the reserve bit so I stepped through the
following piece of the code
//further up in the code input buffer is set
inputBuffer = new byte[Constants.DEFAULT_BUFFER_SIZE];
//calculation of reserve
int b = inputBuffer[readPos++];
fin = (b & 0x80) > 0;
rsv = (b & 0x70) >>> 4;
if (rsv != 0) {
// Note extensions may use rsv bits but currently no extensions are
// supported
throw new WsIOException(new CloseReason(
CloseCodes.PROTOCOL_ERROR,
sm.getString("wsFrame.wrongRsv", Integer.valueOf(rsv))));
}
However I have noticed when the line "int b = inputBuffer[readPos++];"
it sometimes changes the value of the reserve bit from 0 to a number
between 1-7. Why would this be changing the reserve bit? Is this
possibly an error with what I am doing or an error due to the class
from tomcat that is running?
