Embedding an nREPL server in lwjgl example results in crash on connection attempt about skija

Finally getting back into this. 0.6.18 works fine for me. Thanks!

I tried the same approach using the clojure.core.server/start-server instead of nREPL, and when I tried to connect, it crapped out with a similar message:

# Problematic frame:
# C  [libskija.dylib+0x4502d]  SkCanvas::internalDrawPaint(SkPaint const&)+0xcd

Very strange. I can reproduce it, and it seems to be related to Skija specifically, if I remove it and leave LWJGL only, it doesn’t crash. I’ll look into it too, thanks for reporting!

I think the problem is that connecting via nREPL triggers GC which collects BackendRenderTarget and Surface. Adding (println context target surface) after the infinite loop solves the problem. I’ll fix Skija tomorrow so that Canvas holds a reference to the Surface so that it won’t be collected before Canvas is.

Should work fine in 0.6.14. Let me know if it doesn’t
