How to get the IDE debugger to use the OpenJDK source code instead of the decompiled class files?

[Anil]

Yay! that worked. Thanks.
Is it possible to add a section to that docs page about using an IDE
debugger?
It was not obvious that one should use
...\OpenJDK\jdk\build\windows-x86_64-server-release\images\jdk instead
of ...\OpenJDK\jdk\build\windows-x86_64-server-release\jdk
to connect the jdk source files to the debugger.
