Where have all the "fastdebug" builds gone?

[Volker Simonis]

Hi,

I could have sworn that

http://jdk6.java.net/download.html and
http://jdk7.java.net/download.html

always contained product AND "fastdebug" builds, but as I just
verified today there are no more "fastdebug" builds available neither
for JDK6 nor for JDK7 and JDK8.

Is this intentional?
Is there any other source for debug builds of the original Oracle JDK?

The debug builds have always been very useful to track down problems,
especially because many of the diagnostic VM options are only
available in debug builds.

Regards,
Volker
