[cross-project-issues-dev] Re: [HeliosAggregation] Failed for build 2010-05-19_23-11-20 (FIXED)


Hi Christian. Glad you got it working, even if took some "manual" intervention.

So, you manually "... did a -repack of the original cononical.jar, then a signing, then pack200 " and all is well.
Just to be sure, that is what you do each time, right? For every jar? Every build?  Those are indeed the correct, required 3 steps: -repack (conditioning), then sign, then pack200. (all with Java 5).
And, I assume you do this for all your jars, and all others work ok with no noise?

Do you do anything with the specifiable properties to control the pack process? I know some use -E4 since that was recommend by Sun in some early work to avoid some particular problem with corrupt files. So, if you don't , you might use -E4 to see if it helps .... and. ... my initial point .... if you use parameters at all, you must use exactly the same ones for the repack step, and the pack200 step. It'd be hard not to, using all the standard stuff ... but, I bet you do not use all the standard stuff? :)

For the -E4 recommendation, see  "workaround to downgrade pack200 effort to -E4"
described in
https://bugs.eclipse.org/bugs/show_bug.cgi?id=154069

Do you happen to have jars inside this jar? Embedded jars? That can raise other complications ... which I'm too tired to recall at the moment.

And, last of all, there are some few cases of jars where pack200 does not work ... particular patterns of class file code that the tools do not quite handle correctly. They are rare, but I think TPTP had one of those. So, in a case like that, you need to mark it "do not pack", but still have it signed.

But in those cases, it always failed. It kind of sounds like you have intermittent results, which is very odd (i.e. don't recall hearing that, before).

So, I'll send this to cross-project also ... there's many experts on that list that  could maybe know right away what the problem might be.

Good luck next week.


Thanks,

hi David,

thanks for the hints you gave me. I managed to twiggle around with the riena.tests....pack.gz and make it work in the helios aggregator build. You now have a blue build (for the first time for quite some time).

About the "twiggeling":
I was able to verify that its not a java5/java6 problem we run everything with java5. I also was was able to unpack200 the original riena.tests pack.gz file. However when trying to pack200 that resulting jar again I got the same error that the MessageBoxRidgetTest$2.class had an invalid SHA1. So I manually (using JDKs tools) did a -repack of the original .jar (that came out of our build process when we did the RC1), then a signing, pack200 and only replaced the pack.gz file for riena.tests in our update site and that did the trick.

So I know a workaround, still dont understand what is causing this problem that is only happening in one bundle (which is particularly large)

Yes, you can start it. I'm about to send a note to cross-project now, setting a hard deadline of 10 am eastern, for Thursday.

that sounds like something I can figure out......(the java6 thing is quite possible)......Can I start the helios.agregator hudson build job when I am confident that its fixed ? (since you probably are about to go to sleep, and it will take me another hour to get to the office) ???

It comes from trying to unpack200 the org.eclipse.riena.tests...jar.pack.gz file.
You can try it your self, on your pack.gz file.
If it passes with unpack200 from Java 6 JDK, but fails with unpack200 from a Java 5 JDK, then I could guess at the problem:
That you pack200 using Java 6.
In some cases, this is fine ... but, in several cases, it will create a pack.gz file which is incompatible with Java 5
(and we intentionally use Java 5 to unpack, and do this verification).

Other than that, it might indicate some problem with "conditioning" (preparing for pack200). I don't recall this specific error for those types of problems ... but, only other thing I an think of.

Why don't you try unpack200 yourself, and report back what you find.

hi david,

do you have any hint what I can do to fix this.......I mean I didnt tamper with that specific bundle or change it after signing it. Is it the pack200 file that it finds the error or the .jar file ?
