Hi, I'm doubtful this is an issue specific to AIX since I'm seing this now on a Linux box. See below.

FWIW, I'm seeing this issue now on the Zero builder: http://builder.classpath.org/jenkins/job/OpenJDK9_hs_rt_Zero/203/console The builder might be under load which could cause this, but nevertheless it's the first time I'm seeing this. Has the above code been introduced recently? Is there a bug I can CC myself to? Thanks, Severin
