Work-around for [#56](https://github.com/Insubstantial/insubstantial/issues/56) as suggested in [#56#issuecomment-333986024](https://github.com/Insubstantial/insubstantial/issues/56#issuecomment-333986024).
Java 11: disable augmentation Since Java 11, Java bytecode is required to include some additional metadata. The bytecode generated by laf-widget for "augmentation" of other widget libraries does not follow this requirement, resulting in a build failure.
A later version of laf-widget has removed this augmentation rather than fixing it: https://github.com/kirill-grouchnikov/laf-widget/commit/8b0871e84ca6b6c0c479a6033998eb39e0fc767d
This augmentation does not seem to be essential, so disable it until it is fixed or properly removed.
