Specifying limited set of SSL Ciphersuites doesn't seam to work

Hello everyone, 

I'm trying to react on a security scan where one of the findings was weak ciphers for WebLogic SSL connections. 

After a bit of investigation I found few cipher suites which are strong and I want my WebLogic instances to use only those. 

To do so I specified: 

-Dweblogic.security.SSL.Ciphersuites=TLS_RSA_WITH_AES_128_CBC_SHA,SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA,SSL_RSA_WITH_3DES_EDE_CBC_SHA

on the Java command line (server start). With all SSL debug options I get the following output in the log: 

...

weblogic.security.SSL.Ciphersuites = TLS_RSA_WITH_AES_128_CBC_SHA,SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA,SSL_RSA_WITH_3DES_EDE_CBC_SHA
