Hi Prasant,

This looks suspiciously related to  If so, this bug *should* 
be fixed in Monocle but it is not (and will not be) fixed in lens.

I believe you are building openJFX, correct?  If you can try a recent 
build with the latest Monocle code (if you are building from OpenJFX, 
monocle is now the default) the problem should be resolved. Please let 
us know if that's not the case.
