Apparently Android O will support MethodHandles.
Is there a simple way to compile a kawa.jar against 1.6, so I
can use it for Android?
You need to build Kawa from source, using the configure flag
--with-android=/path/to/android.jar
These instructions should help; however, they are a bit out-of-date:
https://www.gnu.org/software/kawa/Building-for-Android.html
(Advice for updating the instructions would be very welcome.)
2) In the following code, I get a kawa segfault. It seems to be related
to the anonymous inner class, if I factor that out, things work fine.
...
Is this somehow my fault, or is this a bug in the compiler?
Could be both :-)
As a general rule, any segfault or NullPointerException in the compiler is a compiler bug.
(I don't count exceptions in for example user-written macro transformers - however,
the compiler should catch those and print a helpful error message.)
Sometimes a compiler bug is triggered by a bug in the application.
I was able to reproduce the NullPointerException, so I'll take a look later.
