      Environment

      DC, 2 nodes

      Steps to Reproduce

      Node A - node with debug port opened
      Node B - node w/o need of debug port

      1. Start cluster
      2. On Node A attach a breakpoint in com.atlassian.jira.issue.fields.config.persistence.FieldConfigSchemePersisterImpl#update, before line storeConfigAssociations
        • Make sure breakpoint will suspend thread, not whole JVM
      3. Still on Node A via browser, try to attach new issue type to issue type scheme via "Modify Issue Type Scheme" screen:
        1. Create new issue type
        2. Go to "Issue type schemes"
        3. Click "edit" on some scheme
        4. Move created issue type from "Available Issue Types" column to "Issue Types for Current Scheme"
        5. Click Save - breakpoint should be hit
      4. In Node B open Create issue Dialog making sure that active project uses scheme we are trying to modify
        • Note: Sometimes despite breakpoint caches are propagated between nodes. To force node B to load data from DB, we can invalidate caches before opening dialog
      5. Review actual behaviour - see Actual Results below:

      Expected Results

      No exceptions should be thrown

      Actual Results

      Dialog breaks, with stacktrace visible in the console:
