Please make sure to provide your reproducible project. I am sure you should have edited Metadata.xml to get less compile errors, otherwise it won't compile up to get any error like that. Thanks.

Ah, ok I misunderstood you, you quoted just one out of those bunch of build errors. It's not a bug, you get those errors because there is a "handle" field which became "Handle" property and hence conflicted with Java.Lang.Object.Handle property (managed-only property). Hence you need to use this kind of metadata.xml - it renamed Handle property as HandleField property:

  <attr path="/api/package[@name='com.ftdi.j2xx']/class[@name='D2xxManager.FtDeviceInfoListNode']/field[@name='handle']" name="managedName">HandleField</attr>

I verified this jar binding builds with 4.4.55.
