Re: [Jython-dev] JDK 9 EA Build 162 is available on java.net

[Jeff A. <ja...@fa...>]

I tried Jython compiled on 7, run on 9, using the Windows 64-bit JDK.

The most obvious problem is with Netty class-loading. The effect is very 
close to this: https://github.com/netty/netty/issues/6246, so it seems 
like a recurring one for them, maybe related to security management and 
the class path. I haven't delved further. "import socket" is the easiest 
way to trigger it, and it occurs as a result of  "from io.netty.buffer 
import PooledByteBufAllocator" in _socket.py.

When I build on Java 9, I get non-fatal error messages from ANTLR that I 
think are the same as on Java 8. And then a lot of deprecation warnings, 
including Class.getInstance(), and wrapper type constructors e.g. 
Integer(int). Hard to say if there are runtime problems as the Netty one 
stops us running the regression test.
