After debugging I can see that it is the List StandardChangeLogHistoryService.ranChangeSetList that is set to null when ant is executing the tag(final String tagString)-method.
The NullPointerException occurs when this row is executed: ranChangeSetList.get(ranChangeSetList.size() - 1).setTag(tagString);
When trying to add a tag to a database with several rows in the database changelog table the following stacktrace is returned:
[echo] Adding tag before-3.16.8
[tagDatabase] INFO 6/25/14 8:34 AM: liquibase: Successfully acquired change log lock
[tagDatabase] INFO 6/25/14 8:35 AM: liquibase: Successfully released change log lock

The tag is added with the ant task tagdatabase before any new changesets are applied.
