WebSocketSession#getHandshakeHeaders is unsafe probably

[michaldo]

Spring Boot version 4.0.3 with Tomcat

I sometimes see the following error in code session.getHandshakeHeaders().getFirst(HttpHeaders.USER_AGENT)

java.lang.IllegalStateException: The request object has been recycled and is no longer associated with this facade
	at org.apache.catalina.connector.RequestFacade.checkFacade(RequestFacade.java:609)

I happens suddenly, I can't provide any context

But ChatGPT says that Tomcat recycles Http Request and calling session.getHandshakeHeaders() is not safe in afterConnectionEstablished()
