RuntimeError: Constants DL and Fiddle is not defined.

[Arakaki]

I report RuntimeError here. Might need to fix to support JDK version 11 or more.

• error log

  RuntimeError:
  Constants DL and Fiddle is not defined.
  ...
  # Fiddle::DLError:
  #   /usr/lib/jvm/java-11-openjdk-amd64/jre/lib/amd64/server/libjvm.so: cannot open shared object file: No such file or directory

• cause JDK 11+ do not include jre so can not open libjvm.so file. https://github.com/arton/rjb/blob/faee51fad1a4f7cf608bfe0485d8cc244b6a6991/ext/load.c#L90

• temporary solution

  ln -s /usr/lib/jvm/java-11-openjdk-amd64/lib/server /usr/lib/jvm/java-11-openjdk-amd64/jre/lib/amd64/server

• environments

  • JDK: JDK11
  • Ryby: 2.5.5
  • OS: Linux
