The message resource "java.panel.about.border" seems to be also used
in "About..." button on Java tab of ControlPanel.

Deployment.java:

        { "java.panel.about.border", "About" },
        { "java.panel.about.mnemonic", "VK_B" },

The message resource "java.panel.about.border" should be used only for the
border not for the button. It should be like:

        { "java.panel.about.border", " About " },
        { "java.panel.about_btn", "About..." },
        { "java.panel.about_btn.mnemonic", "VK_B" },
