There is a redundant call to Math.min in method
jdk.internal.net.http.Http2ClientImpl#getConnectionWindowSize
https://github.com/openjdk/jdk/blob/master/src/java.net.http/share/classes/jdk/internal/net/http/Http2ClientImpl.java#L240

int defaultValue = Math.min(Integer.MAX_VALUE,
        Math.max(streamWindow, K*K*32));

Call of method Math.min(int, int) is redundant if one of parameters is
known to be Integer.MAX_VALUE (or Integer.MIN_VALUE)
