I never said it was rare or not. It is possible if you truly need fast startup times. The fact of the matter, the JVM is good enough for the vast majority of the use cases, and is faster than golang so no need to even go there.
Not a joke. Large real world programs are proof (otherwise, my employer will not be spending millions of dollars on reinventing performance and other toolings already present in the JVM). What golang gui programs are you comparing against?
Java CLI tools compiled with GraalVM start up just as fast.
Nice joke. Go software runs much snappier and faster than any Java GUI or CLI tool.
