What did you expect to see?

Reduce time, or can be pre-compiled

You can invoke Fury to generate serializer code to java files first, then compile it with your project together:

BaseObjectCodecBuilder codecBuilder = new ObjectCodecBuilder(cls, fury);
String code = codecBuilder.genCode();
Files.write(new File(codecBuilder.codecQualifiedClassName(cls).replace(".", "/") + ".java").toPath(),
      code.getBytes(StandardCharsets.UTF_8));

Async compilation can be used for such cases too, it will compile generate serializer in background, and the serialization will use intepreter serializer before compilation finishes:

Fury fury=Fury.builder()
  .withLanguage(Language.JAVA)
  // enable reference tracking for shared/circular reference.
  // Disable it will have better performance if no duplicate reference.
  .withRefTracking(false)
  .withCompatibleMode(CompatibleMode.SCHEMA_CONSISTENT)
  // enable type forward/backward compatibility
  // disable it for small size and better performance.
  // .withCompatibleMode(CompatibleMode.COMPATIBLE)
  // enable async multi-threaded compilation.
  .withAsyncCompilation(true)
  .build();
