This issue is probably related to SPIGOT-914 (the third stacktrace given there), which is marked as duplicate of SPIGOT-461, which is marked as fixed.
However, the following is still not fixed:
[07:32:39] [Craft Scheduler Thread - 88/WARN]: Exception in thread "Craft Scheduler Thread - 88"
[07:32:39] [Craft Scheduler Thread - 88/WARN]: org.apache.commons.lang.UnhandledException: Plugin Paintball v1.3.4 generated an exception while executing task 188525

The issue here is probably that SimpleDateFormat.format(..) is not thread-safe.
