I am using java + scala (with sbt ) in one project.
Language Information:
nazar@lelyak-desktop:~⟫ java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)
nazar@lelyak-desktop:~⟫ scala -version
Scala code runner version 2.10.4 -- Copyright 2002-2013, LAMP/EPFL
When I run any main(), I received a strange warning:

I could not understand this behavior.
UPDATE:
I checked the options sbtthat it has the same behavior:
nazar@lelyak-desktop:~⟫ sbt -version
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256M; support was removed in 8.0
Thanks for explaining so quickly new features for java 1.8!
But how to solve the warning MaxPermSise?
here is the content idea.vmoptions:
-server
-Xms128m
-Xmx512m
-XX:MaxPermSize=250m
-XX:ReservedCodeCacheSize=64m
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djsse.enableSNIExtension=false
-XX:+UseCodeCacheFlushing
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-Dawt.useSystemAAFontSettings=lcd
Eclipse has eclipse.ini:
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library

-XX:MaxPermSize=256m
-Xms40m
-Xmx1024m
-Dorg.eclipse.swt.browser.IEVersion=10001
UPDATE2
I deleted all lines containing from both configuration files MaxPermSize.
But this error warning remains (at startup main()and run sbt -versionon the terminal).
?
