Checking the logs on a production system, I can see this exception being thrown as early as March 2021; there are no older logs on the system. At that point the system was running OpenGrok 1.6.3, so this is definitely not introduced in the recent versions. Also, the removal of the optimization step was done in 1.7.35 (#3983 mentioned above) so that hypothesis is not viable either. Looking into the logs, this is happening every now and then - several times per month. This system has been running the indexer (in per project workflow) every 4 hours for bunch of years. |
