OperatorImportFromESRIShape causes java.lang.OutOfMemoryError

Hi together,

currently I play arround with your geometry-api-java (version 1.2.1 from maven) to read an entire shape file and stumbled over the following issue:

```

```

The below snippet shows how I try to read the shape file.

```java
public List readShape(InputStream shape) throws IOException
{
List geometries = new ArrayList<>();

ByteBuffer bb = ByteBuffer.wrap(IOUtils.toByteArray(shape));

GeometryCursor cursor = OperatorImportFromESRIShape.local().execute(0,
Geometry.Type.Unknown, new SimpleByteBufferCursor(bb));

Geometry geometry;
while ((geometry = cursor.next()) != null)
{
geometries.add(geometry);
}

return geometries;
}
```

I Hope you can help me out with my problem. I also attached the shape file.
