Well, we finally got a green build a few hours ago so that I was able to 
promote a new 'staging' repository. Those of you who are "done" should 
verify it is as you expect. 
And, still 5 hours or so to go before the deadline, so I expect things to 
turn our ok.  As always, keep us informed of any problems.

(Still a lot of legal files missing, still a lot of unsigned jars from 
BIRT).

Issues around "pack200": 

I know many of you had issues revolving around invalid jars produced by 
"pack200", probably related to you changing the VM you build with, to a 
higher version. And, I know at least some of you "turned off" packing, for 
your entire project build. 
Understandable, given the deadlines and the mysteries about why it 
sometimes breaks jars. (Short answer is, I think, just that there are some 
rare combinations of byte codes that reveal bugs in pack200, and that not 
much improvement has been made in pack200 for those rare combinations ... 
but, I do not know for sure how to tell for all cases ... it could be 
invalid byte codes? I could be you are "packing" something that has not 
been conditioned, or, conditioned with a different VM with certain 
parameters set. In general, "conditioning/packing" something that has 
already been conditioned, is not good. 
  pre-condition --> sign --> pack200 is not the same as 
  pre-condition --> pre-condition --> sign --> pack200
This is similar if not directly related to "signing" a jar, that has 
already been signed -- in theory, it can work ... but, in practice you 
have to do it "just right" (so, I advise not to re-sign a bundle, that has 
already been signed.

I hope everyone, who has "turned off" packing completely will reserve some 
time during M7 to turn it back on for their project's build, and turn it 
off for only the jars that have problems. Here's a few current 
"statistics" that don't speak too well, of the quality of our repository, 
from one of the repo reports. 

   Check of packed and not packed bundles.

Mars M6
   Number of jar files 5682
   Number of pack.gz files 3096
   Difference, number of jar files to check: 2586
   Checked 2586 of 2586.
   Errors found: 883
 
Luna SR2
   Number of jar files 5440
   Number of pack.gz files 3372
   Difference, number of jar files to check: 2068
   Checked 2068 of 2068.
   Errors found: 467
 

At first I thought those numbers for Mars looked pretty bad, but then 
compared to Luna, and see they were not great But, even compared to "not 
great", the number of unpacked jars has nearly doubled in Mars M6. 
I am not sure (did not measure) what what translates into in terms of 
"extra bandwidth required" but if you haven't heard yet, our bandwidth is 
already pretty full -- so, please do your part to minimize that. 
See the report for details. 
http://build.eclipse.org/simrel/mars/reporeports/reports/pack200data.txt
It is the "long runs" of jars from "one name space" that indicates a 
project has turned it off completely. 
And, to clarify the above statistics, not every jar has to be "packed" ... 
it does not help much, if the jar file does not contain Java class files, 
so it is the "errors" that indicate a jar file with class files, that is 
not packed. 
The others are presumably "resource only" jars (or feature.jars, which 
have no class files.). 
I hope these wordy explanation helps you understand why it is important, 
and how you can help keep it from getting out of control. 

Thanks,
