Description

The stacktrace of the call shows something like

20.05.2014 11:13:07.428 *ERROR* [OsgiInstallerImpl] com.adobe.granite.installer.factory.packages.impl.PackageTransformer Error while processing install task.
java.lang.IllegalStateException: Unexpected value record type: f2

The blob store was configured correctly and according to the log also correctly initialized

Under which circumstances can the length within the SegmentBlob be invalid?
This only happens if a File Blob Store is configured (http://jackrabbit.apache.org/oak/docs/osgi_config.html). If a file datastore is used, there is no such exception.
