The error ocurred in a Java™ access function. Either an Exception was thrown and the function was not called within a try statement or vgVar.handlesysLibraryErrors is 0, or something other than an Exception was thrown, such as an Error.
Use information in the error message to correct the problem. If some kind of Exception was thrown, change the program logic to handle the error by calling the Java access function within a try statement, or by setting vgVar.handlesysLibraryErrors to 1 before invoking the Java access function.
