WebSphere Portal 8. EJPFD0050W: An exception occurred while checking installation history, no information about interim fixes and fix packs is available!

After installing WebSphere Portal 8 I've got the message: 

[7/28/14 13:30:00:488 MSK] 00000019 ProductServic W com.ibm.wps.services.product.ProductServiceImpl init EJPFD0050W: An exception occurred while checking installation history, no information about interim fixes and fix packs is available!


First, I tried this way:

http://www-01.ibm.com/support/docview.wss?uid=swg21634233

But no result because my warning message had NullPointerException instead of the article. 

Then I thought that there are not any necessary files.
I compared my new installation with old one.

In the new installation I did not find two files -  <WSP_Home>/version/installRegistry.xml and installed.xml

It's possible take them from the folder /var/ibm/InstallationManager if you installed WSP under root or from /home/<user>/var/ibm/InstallationManager>

 After that - no warning:
