FULL PRODUCT VERSION :
ADDITIONAL OS VERSION INFORMATION :
AIX HY-AIX64 1 7 000562E4D700
A DESCRIPTION OF THE PROBLEM :
In src/solaris/native/sun/nio/ch/DatagramDispatcher.c,
Java_sun_nio_ch_DatagramDispatcher_readv0 will invoke recvmsg(int socket, const struct msghdr *message, int flags) system call and Java_sun_nio_ch_DatagramDispatcher_writev0 will invoke sendmsg(int socket, const struct msghdr *message, int flags) system call. The msghdr structure differs from Solaris and other platform and it can be initialized on all platforms with setting 0 in this structure.
REPRODUCIBILITY :
This bug can be reproduced always.
