1. Install Liferay 7.2 with fixpack 8

2. Create 200+pages, every page with multiple portlets (Asset Publisher, Web Content display, etc) -> the summary of portlet count should be 300+

3. Create an article.

4. Add an asset publisher to any page.

5. Configure asset publisher to open asset entry full content.  

6. Make sure the article you created at step 3 is visible in asset publisher.

7. Open article full content using link in asset publisher you created at step 4. 

8. Start monitoring jvm. Press F5 repeatedly for ~20 seconds on the page you opened up at step 7. Stop monitoring jvm.

9. Search for key words "isShowContextLink", PortletImpl.clone.

Actual result: The CPU usage is really high.
Expected result: The CPU usage is normal.
