ADDITIONAL SYSTEM INFORMATION :
System / OS is irrelevant
Java version: any since 11
A DESCRIPTION OF THE PROBLEM :
HttpHeaders.firstValueAsLong uses mapToLong in combination with Long::valueOf, see https://github.com/openjdk/jdk/blob/master/src/java.net.http/share/classes/java/net/http/HttpHeaders.java#L97C9-L97C16. Since mapToLong accepts a ToLongFunction, this unnecessarily boxes to Long just to auto-unbox again. Replacing Long::valueOf with Long::parseLong would give a (small) performance improvement.
