Fixed problem

Problem Short description Description Steps to reproduce

Analytics Data API

PRB1945218

 Memory leak of JSON serializer in multivis API Each time a data request is processed, a new serializer is created and not released unless a GC is performed, which causes a memory leak.
  1. Create a dashboard.
  2. Add a tab and add 50 identical single score vis:
    • Source: incident.
    • Condition: sys_id is empty.
  3. Duplicate the tab 9 times so there are 500 visualizations in total.
  4. Disable the property 'com.snc.dashboard.streaming.enabled'.
  5. Stop the instance and start again, but don't access the instance in the browser.
  6. Use VisualVM to capture the heapdump.
  7. Search for 'IntegerDateSerializer' in the object list.
    • Observe that there are 0 results.
  8. Access the dashboard created in step 1.
  9. Go over all 10 tabs.
  10. Use VisualVM to capture the heapdump.
  11. Search for 'IntegerDateSerializer'.
    • Observe that there are ~500 results.
  12. Repeat steps 8 through 11 (get the heapdump and search).

Observe that there are ~1000 results. Each time a data request is processed, a new serializer is created and not released unless a GC is performed, which causes a memory leak.
