And, I forgot to say, Netbeans returns hundreds of errors with the
source covered in red underlining, with messages like "error: package
jdk.vm.ci.code does not exist".  It does, and it's in the JDK, but for
some reason Netbeans doesn't look in there.  So I can't set breakpoints
on it either, because I get the

Not able to submit breakpoint MethodBreakpoint [jdk.tools.jaotc.Main].main '([Ljava/lang/String;)V', reason: Breakpoint belongs to disabled source root '/home/aph/jdk/src/jdk.aot/share/classes/jdk.tools.jaotc/src'. See Window/Debugging/Sources.

message.  I was hoping that the Netbeans projects would fix this.

Like I said, lots of people are working on the JDK, and they must do
their development somehow.  But it seems impossible.  The Netbeans
projects don't work -- I guess they got broken when the source was
reorganized.  I'm going to try John Rose's suggestion next, to see if
that works.
