6772303: (se) IOException: Invalid argument" thrown on a call to 
Selector.select(value) with -d64

This is Solaris and 64-bit specific. In summary, the DP_POLL ioctl used 
to retrieve events from the /dev/poll driver limits the number of pollfd 
entries in the poll array to the maximum number of file descriptors 
minus 1. The /dev/poll Selector uses this limit or 8k (whichever is 
smaller) to size its poll array. This sizing breaks for the unlimited 
case on 64-bit because RLIM64_INFINITY is negative (-3) and also the 
code is truncating the limit to a jint. This manifests with the select 
method throwing IOException "Invalid argument". There are many ways to 
fix this, one of the simplest being to treat infinity as Integer.MAX_VALUE.
