"Manage Certificates" button missing in Java Control Panel w/german locale

FULL PRODUCT VERSION :
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux


EXTRA RELEVANT SYSTEM CONFIGURATION :
The problem happens with a german locale.

A DESCRIPTION OF THE PROBLEM :
The Java Control Panel has the button "Manage Certificates" under the "Security" tab. This is necessary to provide custom certificates.
However, this button is missing when using a german locale.

As an example:
   LC_ALL=POSIX works fine. The button is visible
   LC_ALL=de_DE.UTF-8 doesn't work. The UI is in german, but the button is missing.

EXPECTED -
There should be 3 buttons visible:

  * "Zertifikate verwalten" ("Manage Certificates")
ACTUAL -
Only 2 buttons are visible:

CUSTOMER SUBMITTED WORKAROUND :
The only workaround is using a locale different from german (for example it_IT.UTF-8 works).
