@bazo; thank you for reporting.

This was due to logging level used when trying to replace hardcoded fields (mostly colors to match dark LAF) in some classes with reflection. In some cases those classes may not be available (for example a NetBeans Platform application probably will not contain Visual Form Designer module and hence LayoutPainter class as in this exception) and this is quite normal. So log level should be INFO instead of WARNING and should not cause a dialog to be displayed.

This is already fixed in 9c4a62a and will be available in v1.4.
