java.lang.OutOfMemoryError: PermGen (GWT + NetBeans + Maven)

Question

I am working on GWT + NetBeans + Maven project and I keep getting out of memory error. I am running the project simply by executing gwt:debug goal.

I tried to set higher memory limits in pom.xml like this:

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>gwt-maven-plugin</artifactId>
            <version>${gwt.version}</version>
            <executions>
                <execution>
                    <goals>
                        <goal>compile</goal>
                        <goal>test</goal>
                    </goals>
                    <configuration>
                        <modules>
                            <module>cz.bull.iui.User</module>
                            <!--<module>cz.bull.iui.Login</module>-->
                        </modules>
                        <localWorkers>4</localWorkers>
                        <extraJvmArgs>-Xmx1024M -Xss1024k -XX:MaxPermSize=1024M</extraJvmArgs>
                        <localWorkers>4</localWorkers>
                        <draftCompile>true</draftCompile>
                        <logLevel>INFO</logLevel>
                        <failOnError>false</failOnError>
                        <hostedWebapp>${project.build.directory}/${project.build.finalName}</hostedWebapp>
                        <style>OBF</style>
                    </configuration>
                </execution>
            </executions>
        </plugin>

But the problem still occurs:

GWT development Mode console Could some advise me, where do I have to set it, so GWT gets enough memory? By checking Task manager I can see Development Mode console is using about 500MB at the occurrence of crash, which is less than defined.

Just guessing, maybe if you try with 'm' instead of 'M'? (like -Xmx1024m -XX:MaxPermSize=384m), huh? — apanizo, May 05 '14 at 13:46

I use NetBeans in this case. – TondaCZE May 05 '14 at 16:13
I don't think throwing random topics on me is gonna help me. Believe me, I did some research myself. Why do you think this is a problem of NetBeans, GWT Development Mode/Jetty is running in it's own process I think. Did some of those helped you with GWT project on NetBeans? – TondaCZE May 05 '14 at 16:33
There is no way this is gonna work, GWT is not running inside NetBeans process. – TondaCZE May 06 '14 at 15:44
GWT application is running in Jetty in DEV mode and I have already shared you a link to set the arguments of Jetty itself. There is lots of response. Please check the answer given by @Binita Bharati. Set `MAVEN_OPTS` – Braj May 06 '14 at 16:01
Follow the link carefully and read all the response. You will definitely get the answer. – Braj May 06 '14 at 16:06
I have the MAVEN_OPTS stetted (-Xmx1024m) but the problem still remains. – TondaCZE May 21 '14 at 12:50

The only good answer is to switch to Eclipse, it just doesn't work with NetBeans.
