Hi Eric, short question, are other platforms beside Linux affected or is this Linux-specific (I saw you said Windows x64 showed no regression)?
Reason I ask is, we just changed the default for AIX to "internal" because this is the only configuration we support and the build was broken after JDK-8036003 (see https://bugs.openjdk.java.net/browse/JDK-8145560) Kind Regards, Thomas On Wed, Dec 16, 2015 at 10:34 PM, Erik Joelsson <erik.joels...@oracle.com> wrote: > Hello, > > Please review this quick fix for the build issue introduced in Hotspot by > JDK-8036003.
