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

[Chen Liang]

Hi Anil,
If you want to use your local JDK, first build with "make images" and then
add the JDK in this directory:
<JDK git repo>/build/<config name>/images/jdk
"config name" should be chosen by you or configure, looks like
"windows-x86-64-server-release"
Note there's an exploded jdk at /jdk instead of /images/jdk; the one not in
images is exploded and does not have sources.

Regards
