After having installed the Documentum Administrator, one of our test was to open a document. When I opened one for the first time the content was empty although I knew it contained text. But the correct content was well displayed when I opened it a second time.

In the ucf trace file I had:

FINE: sun.net.www.MessageHeader@108565d6 pairs: {null: HTTP/1.1 500 Internal Server Error}{Server: Apache-Coyote/1.1}{Content-Type: text/html;charset=utf-8}{Content-Length: 3437}{Date: Mon, 27 Jan 2014 12:55:47 GMT}{Connection: close} Jan 27, 2014 1:55:47 PM com.documentum.ucf.client.logging.impl.UCFLogger error

Solution

To solve the issue, I had to replace in acs.properties:

java.security.provider.class.name=sun.security.provider.Sun 
to
java.security.provider.class.name=com.ibm.jsse2.IBMJSSEProvider

and

java.security.provider.name=SUN
to
java.security.provider.name=IBMJSSE2

EMC validated my workaround, logged an incident report, and reported a regression bug to be solved in future versions.
