Unhandled websocket error when unsolicited pong frame with zero length payload received from IE11 [SPR-12727] #17324
An unhandled error occurs when an unsolicited pong frame with zero length payload is received from IE11. I'm using Spring Framework 4.1.4 and Jetty 9.2.6.
It seems that Jetty returns a null payload when an unsolicited pong frame is received and Spring cannot handle this.
