Modularise legacy jar

• Run "jdeps --generate-module-info" on the legacy jar to generate module-info.java file.

  jdeps --module-path $ROOT_DIR/modules \
        --add-modules jackson.annotations,jackson.core \
        --generate-module-info ~/work $JACKSON_DATABIND_JAR
  

• Unjar the legacy jar, add module-info.java from above, re-compile and re-jar:

  javac --module-path $ROOT_DIR/modules \
        --add-modules jackson.annotations,jackson.core \
        -d $ROOT_DIR/classes module-info.java
