I have a major problem with the P2 mirroring in Galileo Builder. I would
really appreciate some help pinning it down.
The problem occurs during the mirroring phase. A RawMirrorRequest is
executed to fetch a xxx.jar.pack.gz file and it succeeds without
problems. Next, I try to unpack this jar as a sibling. This also
succeeds on most files, but not all. The problem manifests itself like this:
org.eclipse.core.runtime.CoreException: Unable to unpack artifact
osgi.bundle,org.eclipse.buckminster.maven,1.1.350.r10157 in repository
reading signed content:/tmp/signatureFile5703.jar
Caused by: java.security.SignatureException: Either the manifest file or
the signature file has been tampered in this jar: /tmp/signatureFile5703.jar
It only manifests itself when running Java 5 on the build machine (a J9
for ppc). If I run the same build locally on my machine, pointing to the
exact same repository, everything is fine. Moreover, to verify the
consistency of the file on the actual machine where it fails, I tested
using unpack200 (from the same JVM). That completes without problems and
leaves a resulting jar file. I checked this jar file with jarsigner
-verify <jar> and it claims the file is OK.
So what can happen here that makes P2 complain when unpacking? And why
only with one particular VM? Any ideas are greatly appreciated. I'm
starting to drain out of them.
