When building a Java 8 project with Maven:
mvn clean package
I get this message:
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0
How to remove this message?
Compatibility Guide for JDK 8 says that in Java 8 the command line flag MaxPermSize has been removed. The reason is that the permanent generation was removed from the hotspot heap and was moved to native memory.
So in order to remove this message
edit MAVEN_OPTS Environment User Variable:
Java 7
MAVEN_OPTS -Xmx512m -XX:MaxPermSize=128m
Java 8
MAVEN_OPTS -Xmx512m
The JDK 8 HotSpot JVM is now using native memory for the representation of class metadata and is called Metaspace.
The permanent generation has been removed. The PermSize and MaxPermSize are ignored and a warning is issued if they are present on the command line.
-XX:MaxPermSize=size
Sets the maximum permanent generation space size (in bytes). This option was deprecated in JDK 8, and superseded by the -XX:MaxMetaspaceSize option.
-XX:PermSize=size
Sets the space (in bytes) allocated to the permanent generation that triggers a garbage collection if it is exceeded. This option was deprecated in JDK 8, and superseded by the -XX:MetaspaceSize option.
In JBoss EAP 6.4, right click on the server and open launch configuration under VM argument you will find
{-Dprogram.name=JBossTools: jboss-eap" -server -Xms1024m -Xmx1024m -XX:MaxPermSize=256m}
update it to
{-Dprogram.name=JBossTools: JBoss 6.4" -server -Xms512m -Xmx512m}
this will solve your problem.
I got similar message when running command line mvn (version 3.3.3) on Linux with Java 8.
By opening maven script /$MAVEN-HOME/bin/mvn, found the following line
MAVEN_OPTS="$(concat_lines "$MAVEN_PROJECTBASEDIR/.mvn/jvm.config") $MAVEN_OPTS"
Where $MAVEN_PROJECTBASEDIR by default is your home directory.
So two places you can take a look, first is file $MAVEN_PROJECTBASEDIR/.mvn/jvm.config if it exists. Secondly look at files possibly set up the environment variable MAVEN_OPTS. Candidate files are .bashrc, .bash_profile, .profile and those files included by them such as /etc/profile, /etc/bash.bashrc
I located
export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=256m"
in .bashrc in my system, change it to
export MAVEN_OPTS="-Xmx512m"
issue resolved
in case some one still get this kind of message. Its happen because you add JVM argument when running maven project. Because it is related with maven you can check your pom.xml file on your project.
find this line <argLine>...</argLine>, on my project I also have argument below
<argLine>-Xmx1024m -XX:MaxPermSize=512m -XX:+TieredCompilation -XX:TieredStopAtLevel=1</argLine>
you should replace MaxPermSize argument as -Xms123m -Xmx123m, since MaxPermSize is already deprecated and wont take any effect on your JVM config :
<argLine>-Xms512m -Xmx512m -XX:+TieredCompilation -XX:TieredStopAtLevel=1</argLine>
Please to solve this problem we just have set installed JDK path in
standalone.conf
file which under the bin folder of JBoss\Wildfly Server. To solve this we do the following steps:
Open the standlone.conf file which under JBoss_or_wildfly\bin folder
Within this file find for #JAVA_HOME text.
Remove the # character and set your installed JDK path as
JAVA_HOME="C:\Program Files\Java\jdk1.8.0_65"
Hope this will solve your problem
Thanks

Hello I have got problem I was reading about some solutions and tried some of them and they helped a little. When i was starting Jboss Developer Studio or Eclipse Luna (32bit) I had error could not create Java Virtual Machine. Then in system environment I added _JAVA_OPTIONS with New Variable Value: -Xmx512M and this helped a bit: Now i can run Jboss Developer Studio and Eclipse but when i Start Server in JBoss Developer studio it still gives error:
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified
Picked up _JAVA_OPTIONS: -Xmx512M
I dont know how to solve it. I was looking for reason in Internet and trid a few more things but they didnt help.
I will be very thankful for every help.
I have repaired it by adding in System Environment Variables
_JAVA_OPTIONS
-Xmx512M -Xms64M -XX:MaxPermSize=512m
And then changing options in \jbdevstudio\runtimes\jboss-eap-6.3\bin
appclient.conf.bat
rem # JVM memory allocation pool parameters - modify as appropriate.
set "JAVA_OPTS=-Xms64M -Xmx512M -XX:MaxPermSize=512M"
Now everything works for me.
When I deploy and run my project in netbeans, I am getting this error.. And even after setting up JAVA_OPTS and CATALINA_OPTS in environmental variables as well as in netbeans 'VM options' as -Xms512m -Xmx2048m, I am getting same error.. Please, help me out to sort it out..
Exception in thread "http-bio-8080-exec-2" java.lang.OutOfMemoryError: PermGen space
if you start Tomcat from netbeans the -XX:MaxPerm... must go to server setting not JVM settings (or JAVA_OPTS).
go to sevices tab on the left
expand servers and right click on your tomcat
on the Platform tab, provide the necessary settings under VM options (for example -XX:MaxPermSize=256m -Xmx2048m )
For a minecraft server I'm trying to run the server with more than the standard 512MB RAM. This used to work for me but when I recently installed the server again it stopped working. I use the following command line to run the server:
java -Xms1024M -Xmx2048M -jar TekkitLite.jar
pause
But when I run this script I get the following error:
C:\Users\...\server>java -Xms1024M -Xmx2048M -jar TekkitLite.jar
Picked up_JAVA_OPTIONS: -Xmx512M
Error occured during initialization of VM
Incompatible minimum and maximum heap sizes specified
It seems to me it just doesn't pick up the Xmx argument or something, and I haven't found a solution to fix it anywhere.
My system:
OS: Windows 7 64bit
Java: java7u45(64bit)
RAM: 8G
If anyone has a solution, that would be awesome :)
It looks like you have -Xmx512M set in the environment variable _JAVA_OPTIONS. Clear that and try again.
In Windows 7, this is done like this:
Right-click Computer from the Start menu and choose Properties
Click Advanced system settings > Advanced tab
Click on Environment Variables, find _JAVA_OPTIONS, and select it.
Click Delete
Click OK, and you're done!
I have JBOSS installed in my Windows 7 machine., I can start JBOSS from Eclipse but it doesn't publish and when I try to run the standalone.bat file from the Bin directory it throws this error ,
JAVA_OPTS: -client -Dprogram.name=standalone.bat **-Xms1303M -Xmx1303M** -XX:MaxPe
rmSize=256M -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInter

lone.xml
**Error occurred during initialization of VM**
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
I did research the forum and many are suggesting to change the -Xms1303M to -Xms256M ., I edited the standalone.conf file in an editor but it is not getting reflected and getting the same error again.
Could someone please guide me ?
Most likely, you are using or running jboss on a 32 bit jdk and the memory params are out of range or exceed the limits of a 32 bit jdk. Either upgrade to a 64 bit jdk or add this line in your run.conf in jboss/bin, remove the jvm args from your command line and see if jboss starts.
set "JAVA_OPTS=-Xms128M -Xmx512M -XX:MaxPermSize=256M"
In Windows, it is the standalone.bat file and not the standalone.conf file that must be modified with the new JAVA_OPTS environment variable.
