Hi,
Is there any options or methods that I can pass additional jdk options
to the boot jdk when I configure jdk/jdk? I found
--with-boot-jdk-jvmargs, but I think it is effective during building
the jdk, not configuring the jdk.
I used _JAVA_OPTIONS, but it failed to configure (fail to detect jdk
version). I made a patch:
$ hg diff

This works for me. The _JAVA_OPTIONS is effective during configure. Is
there some other way to do that (without changing the code)? Or
otherwise is it possible to accept this patch?
