| Summary | 0019810: ViewComponent memory leak | |||||||
| Description | Whenever a window in opened and the request reaches the backend (it is not cached in client), a new instance of ViewComponent class is created and it is never cleaned up from memory. This causes heap memory usage to rapidly increase as ViewComponent instances can be heavy (up to 4MB). Attached you can see graphs of part of a heap dump suffering this issue. | |||||||
| Steps To Reproduce | -Execute the attached script that does 25 calls to backed for new windows. -Check heap increases with as many ViewComponent instances as opened windows. | |||||||
| Tags | No tags attached. | |||||||

The fix for this issue makes changes scope of ViewComponent from default to RequestScope. It is riskless as ViewComponent instances are never reused, in this way Weld is aware the instance is not needed to be kept in memory. Test plan: -Execute the test defined in the steps to reproduce and check there are no ViewComponent instances within memory. |
