Hi Volker,
Thanks for the clarification. I have been able to ascertain that
adding full debug symbols to rt.jar would grow the file by 12MB
(uncompressed, probably much smaller after you run PACK200). The
debugging symbols for native code probably cost a lot more than that.
Any idea on why rt.jar does not contain full debug symbols in the
JDK? If I open a bug report for this, is anyone willing to push this
through the system?
Thanks,
Gili

Hi Gili,
the mail threads you mention in your mail refer to debugging symbols
in the native VM implementation (i.e. libjvm.so) and not to debug
symbols in the java classes in rt.jar.
Regards,
Volker

Hi,
Where did the old debug builds of rt.jar go (meaning,
rt.jar with full debug symbols, even for local variables)?
I scanned the mailing list for a related discussion but
couldn't find anything. It looks like somewhere down the
line a decision was made to remove these builds, but it's
not clear why that was. Also, out of curiosity, what is
the overhead of the full debug symbols (versus what we
ship now)? Couldn't we ship a full-debug rt.jar with the
JDK and ship the smaller rt.jar with the JRE?
+1 on shipping debug builds with the JDK, that would be very
helpful for those of us who are stupid^Wcurious enough to
step-debug into JDK classes.
I have personally wasted countless days/weeks/months debugging
problems that would have been solved much quicker by having full
debug symbols. Furthermore, as you can see at
http://mail.openjdk.java.net/pipermail/build-dev/2012-October/006892.html
the GNU/Linux world also ships with full debug symbols by default.
I'd like to take this opportunity to follow-up on
http://mail.openjdk.java.net/pipermail/build-dev/2012-October/006881.html.
I am confused because this post seems to be saying that Oracle JDK
7 ships full debug symbols, but in my experience this is not the
case. It would be good to get some answers from someone in the know.
Thanks,
Gili
