--- Comment #12 from Tony Reix <tony.reix at bull.net> ---
This line:
declare -r jit_opts="-XX:ReservedCodeCacheSize=256m -XX:+TieredCompilation"
appears in file sbt of snappy-java .
I do not master this, and I cannot ask the developper to change it.

If I remove the option  "-XX:+TieredCompilation"  then that works.
So, I'll change the severity.

 - it is wrong that, in my PPC64LE environments, all -XX options are
 - only TieredCompilation seems not implemented. this other options do work:
            -XX:+CMSClassUnloadingEnabled    -XX:+UseConcMarkSweepGC
            -XX:ReservedCodeCacheSize=256m   -XX:MaxPermSize=384m
 - why TieredCompilation is not implemented ?
 - why, instead of crashing the JVM, don't you rather throw a warning message
and continue the execution ? Killing with "fatal" looks like very bad. Instead,
it is only some important feature for speeding up Java start that is missing.
Not a big deal.

So, when do you plan to deliver a full version of OpenJDK on PPC64LE ?
Which other features are still missing ?
