After Jira upgrade to version 9.x.x some worklogs for past periods are not shown

The problem is caused by Safeguards indexing limits that were introduced in Jira 8.22.2: https://community.atlassian.com/t5/Data-Center-articles/Introducing-Safeguards-for-Jira-index/ba-p/2037880#M433.

To fix the problem set -Djira.safeguards.indexing.issue.worklogs in setenv.sh to 0 (index all worklogs) and run the full re-index. It’s recommended to add it to JVM_SUPPORT_RECOMMENDED_ARGS variable. Multi variables should be space separated.
