FileNotFoundException for jackson-module-jaxb-annotations-2.3.2.jar

During startup of openhab2 I found a FileNotFoundException for /var/lib/openhab2/cache/org.eclipse.osgi/194/1/.cp/lib/jackson-module-jaxb-annotations-2.3.2.jar in /var/log/openhab2/openhab.log. When I looeked at the file system I saw that only /var/lib/openhab2/cache/org.eclipse.osgi/194/2/.cp/lib/jackson-module-jaxb-annotations-2.3.2.jar exists.

Is this a configuration or a programming error?
