I'm also refactoring the jdk.javadoc/Gendata.gmk file a bit to better adhere to current build infra standards as this was missed in the original review of this file. Rebuilding should now work better with the various clean targets and any problems with the generation tool will be captured in separate log files, along with the command lines.
