SSP server does not send error codes for bad requests ----------------------------------------------------- Key: JBIDE-26086 URL: https://issues.jboss.org/browse/JBIDE-26086 Project: Tools (JBoss Tools) Issue Type: Bug Components: runtime-server-protocol Affects Versions: 4.6.0.AM3 Reporter: Jan Richter Assignee: Rob Stryker Priority: Major Fix For: 4.11.x Sending a request the server does not like produces no response, it is simply logged on the server side and the client is not notified of what happened. Something like a code 400 would be appreciated. For example, initiating a connection with no content-length header simply logs the following on the server side, but the client is stuck waiting. {noformat}java.lang.IllegalStateException: Missing header Content-Length in input "GET / HTTP/1.1 Sec-WebSocket-Version: 13 Sec-WebSocket-Key: 4vrbTo0+BlSk5wK7si6SWQ== Connection: Upgrade Upgrade: websocket Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits Host: localhost:27511 " at org.eclipse.lsp4j.jsonrpc.json.StreamMessageProducer.listen(StreamMessageProducer.java:89) at org.eclipse.lsp4j.jsonrpc.json.ConcurrentMessageProcessor.run(ConcurrentMessageProcessor.java:95) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748){noformat} This is most likely a 'feature' of lsp4j, thoughts?
