Please disregard this issue - it was some fault on my side. I
re-tested following IDL definition for array function:

sequence < sequence < any > > MyFunc(
     [in] com::sun::star::beans::XPropertySet xOptions
);

With Java implementation

        public Object[][] MyFunc(
                com.sun.star.beans.XPropertySet xOptions
        ) {
            return new Object[][] { {1.1, 2.5}, {3.6, 7.8} };
        }

and it works OK.
