Hi, I wrote as an end user who does not care about the other users. The main question is that is it useful at all to explicitly set MaxMetaspaceSize for Java 8 because there is a system which should set MetaspaceSize to reasonable size automatically. If everything works fine without setting MaxMeatspaceSize then it is probably better not to set it and keep startup files more simple.
However, sooner or later some other user notices the warning as well and asks the meaning of it from the mailing list. Perhaps I will start to care about other users and try to remove the warning by adding a Java version check into the startup.bat for Windows by following the Linux example from https://github.com/sbt/sbt-native-packager/issues/203 and then share the result. I don’t mind if some other user on the list makes it before me. -Jukka Rahkonen- Andrea Aime wrote: Hi Jukka, we cannot simply replace the option, since it's unknown to Java 7: > java -version java version "1.7.0_72" Java(TM) SE Runtime Environment (build 1.7.0_72-b14) Java HotSpot(TM) 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?)

Java HotSpot(TM) 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” ? -Jukka Rahkonen- ------------------------------------------------------------------------------ _______________________________________________ Geoserver-users mailing list Geoserver-users@lists.sourceforge.net<mailto:Geoserver-users@lists.sourceforge.net> https://lists.sourceforge.net/lists/listinfo/geoserver-users -- == GeoServer Professional Services from the experts!
