How do we build debug version of VM

Question

I am getting the following error when i pass the graph level option

"Error: VM option 'PrintIdealGraphLevel' is develop and is available only in debug version of VM."

I am using openjdk 9.

Here is how to Build OpenJDK 8, and the instructions should be the same for Java 9.

You want to enable the FAST_DEBUG option in the configuration.
