CQ5.4: disk is filled with null-resource-*.ser file

Problem

My disk is filled with many files like null-resource-*.ser under crx-quickstart/launchpad/installer

At each restart I detect new files, and so it's growing and may use up to some Gigabytes of those files.

Resolution

Remove the null-resource-*.ser file

To avoid that it create new ones you can update some of the bundles via Apache Felix Webconsole.

The following need to be installed:

org.apache.sling.installer.core: 3.2.3-R1221231
org.apache.sling.installer.factory.configuration: 1.0.3-R1186760
org.apache.sling.installer.provider.jcr: 3.1.1-R1213753
