Hi Matt,
Thank You for your valuable response.
I already checked the CORE-TOOLS version between our Production system and sandbox system, the version exactly match (7.00 SP14 (1000.7.00.14.0.20071210170909).
Just curious here, why on Production the visual admin can be executed by Java 1.4, but on sandbox system the visual admin can't executed by Java 1.4 (error: Caused by: java.lang.UnsupportedClassVersionError: org/GNOME/Accessibility/JavaBridge (Unsupported major.minor version 49.0)
Please share your though or experience Image may be NSFW.
Clik here to view.
Thank You
Edy
