CGBitmapContext.setLineJoin(..) and .setLineCap(..) explode with a NPE

[Gilead]

Calling CGBitmapContext.setLineJoin(CGLineJoin) or CGBitmapContext.setLineCap(CGLineCap) explodes with an NPE:

java.lang.NullPointerException
at org.robovm.rt.bro.ValuedEnum$AsSignedIntMarshaler.toNative(ValuedEnum.java)
at org.robovm.apple.coregraphics.CGContext.setLineCap(Native Method)

java.lang.NullPointerException
at org.robovm.rt.bro.ValuedEnum$AsSignedIntMarshaler.toNative(ValuedEnum.java)
at org.robovm.apple.coregraphics.CGContext.setLineCap(Native Method)

There are a few warnings just before, not sure if related:

WARN: Failed to call getClassTypeID() for the CFType subclass org.robovm.apple.corefoundation.CFType
WARN: Failed to call getClassTypeID() for the CFType subclass org.robovm.apple.coregraphics.CGPath
WARN: Failed to call getClassTypeID() for the CFType subclass org.robovm.apple.coregraphics.CGPattern

Using RoboVM .12

[Gilead]

Just tried with the latest version from source (0e36341) and the error is gone. A different warning appeared, though :)
WARN: Failed to call getClassTypeID() for the CFType subclass org.robovm.apple.coregraphics.CGColorSpace

Anyway, closing as it's not an issue any more.
