commit bef370915b9065aece97e3621645309ddace3a67
Author: James Daugherty <jdaughe...@jdresources.net>
AuthorDate: Sun Jul 19 08:49:34 2026 -0400

    Use a real JDK for GrailsCodecTest (needs Swing/AWT) on 2026.2
    
    Make the test JDK in GrailsTestCase overridable via getTestJdk() (default 
Mock
    JDK 11). GrailsCodecTest's MmmCodec returns javax.swing.JButton/JPanel, so
    getBackground()/getUI() resolution needs java.awt/javax.swing, which the 
minimal
    Mock JDK 11 omits; override getTestJdk() there to use a real JDK.
