> JTS Geometry objects can't be used as return types of compute jobs. Instead, _null_ is
returned. Here's a minimal example showing the bug (and one example that shows that the bug
is sometimes not triggered under slightly different conditions):
>  
> {code:java}
> // this prints "null" (wrong – the expected result would be "POINT EMPTY"):
> igniteCompute.broadcast(() -> (new GeometryFactory()).createPoint()).forEach(System.out::println);
> // this prints "[POINT EMPTY]" (correct):
> igniteCompute.broadcast(() -> Collections.singletonList((new GeometryFactory()).createPoint())).forEach(System.out::println);
> {code}
> This is caused by an invalid _BinaryWriteMode_ of _OPTIMIZED_ in [https://github.com/apache/ignite/blob/ignite-2.7/modules/core/src/main/java/org/apache/ignite/internal/binary/BinaryClassDescriptor.java#L852]
which then leads to a null value to be returned a few lines further down: [https://github.com/apache/ignite/blob/ignite-2.7/modules/core/src/main/java/org/apache/ignite/internal/binary/BinaryClassDescriptor.java#L882]
> From what I can see, the _OPTIMIZED_ mode is set in [https://github.com/apache/ignite/blob/ignite-2.7/modules/core/src/main/java/org/apache/ignite/internal/binary/BinaryClassDescriptor.java#L161]
where the objects are explicitly tested against the _org.locationtech.jts.geom.Geometry_ class.
This could be a regression introduced in https://issues.apache.org/jira/browse/IGNITE-4259
?
