Resolution:
Either remove the offending code or recompile for JVM COBOL code.
Example:
The following example shows the DEFAULT phrase used within an ENUM definition, which produces this error when compiled for other than JVM code:
       enum-id MyEnum.
       78 red value 1.
       78 yellow value 2.
       78 green value 3.
       78 black value 255 default.
       end enum.
