See Caller.java which calls two Immutable-generated builder methods with null-argument.
One is using @java.annotation.Nullable
and it behaves as expected.
The one using @org.jspecify.annotations.Nullable
(see code) causes the call to be flagged as missing @Nullable
:
Annotate the parameter with @javax.annotation.Nullable in method 'appName' declaration, or make sure that null can not be passed as argument.
