This error repeated many times a minute while accessing documentation.
Documentation seemed to be there while this was going on.

The workspace folder has been in use through many upgrades of the Eclipse/STS system so there might be stuff in the configuration setting that is inconsistent.
Guesses:
Configurations created by an earlier version may contain references to options not installed in a later version.
Probably Eclipse making assumptions about files being present because the feature is referenced in a configuration file.
Upgrading using the software Update process is not working very well and it is less trouble to just forget the current version and install a new complete distribution and reapply the optional components.
Eclipse needs to protect itself from lies in the configuration files (or make upgrades work better).
