Don't pass MaxPermSize to Java 8+

[jroper]

Java 8+ does not support -XX:MaxPermSize, and outputs a big ugly error message if you supply it:

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0

The script generated by SBT native packager should not pass a MaxPermSize argument to Java 8 JVMs.

Script to actually get the Java version in bash is a little harder than you might think, because java -version writes to standard error. The following works with JDK6/7/8 on OSX:

( java -version 3>&1 1>&2- 2>&3- ) | sed -n 's/java version "\(.*\)"/\1/p'

Works on Ubuntu, too. I found a shorter alternative

version=$(( java -version 3>&1 1>&2- 2>&3- ) | sed -n 's/java version "\(.*\)"/\1/p')
version=$("$_java" -version 2>&1 | awk -F '"' '/version/ {print $2}')

The last one is already used in the bash script :)

Also on Gentoo and Debian Wheezy.

@kardapoltsev , I'll provide a pull request in a few minutes. You mind take a look?

i installed sbt using Homebrew. I see this warning every time i run my project. I don't think its a problem with the sbt-native-packager but i'm unsure where I should look to silence that warning. Any ideas?

[muuki88]

I think this relates to the sbt-launcher project, which uses a very old version of the sbt-native-packager

@muuki88 thanks. i think sbt/sbt-launcher-package#67 is the right place to follow up so i'll ask my question there.

Hi guy, I am facing this issue and this is how my STS.ini file looks like:

-vm
C:/Program Files/Java/jdk1.8.0_60/bin
-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417
-product
org.springsource.sts.ide
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
512M
-vmargs
-Dosgi.requiredJavaVersion=1.7
-Xms40m
-XX:MaxPermSize=512m
-Xverify:none
-Dorg.eclipse.swt.browser.IEVersion=10001
-Xmx1200m

The message I get is :

What am I missing?

[muuki88]

I think you are on the wrong issue-list here. This sbt-native-packager not eclipse ;)
