when debuging this instance, I see exception at line 130 of SigningInfo.java.
This is slightly differant from reports, in method verifyALlSignedEntriesPresent().
This is because ce.getManifest() is returning null. The jar clearly has a manifest, but ce.getManifest() returns null, even though printing out the ce right after shows ce.getManifest returns non-null immeadiately after.
possibly caused by big fix to 6595845, which trys to lazily load create only weak references to manifests in 6u6
