IllegalStateException in installation process in DynamicCommonJavascript

[heidivanparys]

The log file contains several IllegalStateExceptions when an installation from scratch is done. See log.txt for all the log messages that were generated during installation.

It didn't seem to cause any issues to the installation process itself, so this can probably be considered a minor issue.
