BluetoothLowEnergy.registerProfile(...) crashes simulator under Linux when nRF52840 dongle isn't present

Under Linux, if you attempt to call BluetoothLowEnergy.registerProfile when the nRF52840 dongle isn't connected, the simulator crashes with no explanation. Now obviously without the dongle connected you're not going to be doing any useful BLE development...

Bug: dc.drawArc() when trying to draw arc less than 1 deg starting from 0 draws whole circle

Doing: dc. drawArc ( _centerX, _centerY, _radius , Graphics.ARC_CLOCKWISE, 0.0, // degreeStart 0.5 // degreeEnd ); This ends up with the whole 360deg arc being drawn instead. I'd assume that the arguments are Math.floored and that causes...

I'm developing an app that processes large and deeply nested JSON data structures, where the structure is beyond my control. When handling recursive data, it's easy to hit stack overflow errors. To work around this, I had to rewrite recursive logic to...
