Description

Setting indy="true" causes JavaFX binds to fail on failure to convert
BigDecimal to double. This works ok when indy="false"

=====
"hourAngleProperty.bind((hours() * 30.0) + (minutes() * 0.5))"

this actually translates to this:
hourAngleProperty.bind(hours().multiply(30.0).add(minutes().multiply(0.5)));

where hourAngleProperty, hours() and minutes() are type javafx.beans.property.DoubleProperty.

The problem is the 30.0 and 0.5 are treated as BigDecimal
and with Indy, there seems to be no unboxing of BigDecimal to "double".

If i do this:
hourAngleProperty.bind((hours() * (double)30.0) + (minutes() * (double)0.5))

it works.

But this error is all over the GroovyFX code base.
