Register 0 op in TCPSelectorHandler

[Sebastian Dehne-4]

Hi guys,

I'm trying to run grizzly on a non-Sun JVM and run into a problem which
is caused by registering 0 as an channel operation. The problem is
triggered at TCPSelectorHandler line 462 where 0 is applied as an
argument to register().

SocketChannel.validOps() returns which operations are valid and 0 is not
one of them.

I'm using a patch where I just use SelectionKey.OP_WRITE instead of 0,
which works fine for me and also passes all unit tests.

Any suggestions?


Thanks
Sebastian

Sorry, forgot to mention I'm using version 1.9.15b. This will also match
the line number below. But it seems the same problem exists on trunk.

I think registering 0 should work fine, because it actually means  
deregister *all* interests. Do you see any exception, when registering  
0 interest?

Thanks.
