Hi Jukka,
we cannot simply replace the option, since it’s unknown to Java 7:
java -version
java version “1.7.0_72”
Java™ SE Runtime Environment (build 1.7.0_72-b14)
Java HotSpot™ 64-Bit Server VM (build 24.72-b04, mixed mode)
java -jar -XX:MaxMetaspaceSize=128m …
Unrecognized VM option ‘MaxMetaspaceSize=128m’
To avoid the warning we’d have to first recognize the java version, and then decide
which option to use (or if you to use it at all).
It’s probably not too hard I guess, we’d have to parse the first line of
output in “java -version”, extract the version and setup the options accordingly.
But wondering if we should just leave it be and wait for us to upgrade to java 8 as the
minimum version. On one side, java 7 is unsupported, on the other end, we have
enforced java 7 only recently (starting with 2.6.x if I remember correctly), so not
sure 2.8.x will be a good time to do the switch… maybe 2.9.x instead? (March 2016?)
Cheers
Andrea

Hi,
Geoserver works OK for me with jre 8 but in the beginning of startup this message is printed to the console:
JAVA_HOME: C:\Program Files (x86)\Java\jre1.8.0_40
Please wait while loading GeoServer…
Java HotSpot™ Client VM warning: ignoring option MaxPermSize=128m; support
was removed in 8.0
I read from http://www.infoq.com/news/2013/03/java-8-permgen-metaspace that instead of MaxPermSize Java 8 has a MaxMetaspaceSize but also that Java 8 can also increase the new MetaspaceSize automatically if needed and it is not necessary to set it at all.
I know that the MaxPermSize warning is just a warning but it I however would like to get rid of it with Java 8, would it be better to
a) remove “set JAVA_OPTS=-XX:MaxPermSize=128m” from the Geoserver startup file or
b) edit it into “set JAVA_OPTS=-XX:MaxMetaspaceSize=128m” ?
