Martin, Alan, Joe,

Would you please help review the change (as a workaround) for this "intermittently" problem? https://bugs.openjdk.java.net/browse/JDK-8080803 http://cr.openjdk.java.net/~sherman/8080803 It appears the trigger might be that ByteBuffer.get(byte[]) fails to get the bytes from the buffer "intermittently". Interestingly this one is always reproducible on my local linux build (very old os), in which I have to update couple hotspot headfile to make the build going recently. I filed the bug#8080904 to let the vm guy take a look. Meanwhile the proposed change here is just to "optimized" the ISO2022 code a little to simple workaround this issue. I hope this can make the "intermittent failure" go away in our nightly build. If have time, we definitely should re-visit the implementation of these ISO2022 :-) Hopefully the compiler issue (assuming it is a compile issue) will get fixed soon.

In the mean-time then this looks okay and an extra byte buffer and copy.
