Alright, will do. Thanks for bringing it up.
Do we want to just set up Coverity so that we get these emails directly?

Bosco,
Yes, this is a problem. Thanks for forwarding.
Josh,
You made this change yesterday. Can you please fix?
I see quite a few examples in that file that should be boilerplate. Why does
if (obj == null || !(obj instanceof RpcMetadataResponse)) {
return false;
}
depart from
if (!(obj instanceof RpcMetadataResponse)) {
return false;
}
which is sufficient and is used elsewhere in the file? Boring stuff
should look boring.
In fact the whole method could be simplified. Rather than
public boolean equals(Object obj) {
if (this == obj) {
return true;
}
if (obj == null || !(obj instanceof RpcMetadataResponse)) {
return false;
}
RpcMetadataResponse other = (RpcMetadataResponse) obj;
if (serverAddress == null) {
if (other.serverAddress != null) {
return false;
}
}
return serverAddress.equals(other.serverAddress);
}
there is a case to be made that
public boolean equals(Object obj) {
return this == obj
|| obj instanceof RpcMetadataResponse
&& Objects.equals(((RpcMetadataResponse) obj).serverAddress,
serverAddress);
}
is more understandable as well as more concise.
Elsewhere in the file there is -- not written by you -- the following:
if (null == connectionId) {
if (null != other.connectionId) {
return false;
}
} else if (!connectionId.equals(other.connectionId)) {
return false;
}
return true;
It works, but not obviously so.

Good catch. I know you are monitoring it. Just wanted double sure about it…
Thanks
