review request (M): 7056328: JSR 292 invocation sometimes fails in adapters for types not on boot class path

[Tom Rodriguez]

Overall this looks good.  It's unfortunate we have to jump through so many hoops for this.  What's with these new constants?

+    ETF_FORCE_DIRECT_HANDLE   = 64,
+    ETF_COMPILE_DIRECT_HANDLE = 65,

Are they used over in the JDK side?
