SonarQube - how to turn off Findbugs || JaCoCo || Checkstyle || PMD in Java Quality Profile?

Question

Just started to evaluate SonarQube 3.7.2 for Java projects with configuration 'out of the box',
analysis is triggered from ant.
All works fine but with one big project i got an OutOfMemory Exception, even with -Xmx1024M
SonarQube ships with a Java Quality Profile that combines Findbugs, JaCoCo, Checkstyle and PMD. Didn't find any setting under Quality Profiles > Java Profiles to turn off one of them, only a filter for classname patterns.
Is there any possibility for turning off those tools or do i have to implement my own Java quality rule ?
--EDIT--
Even after using the common rules from Java Quality Rules of the SonarQube online instance - means only 10 rules - i'm getting OutOfMemory Exception. Seems like FindBugs and JaCoCo where running before the exception occured. How to run f.e. FindBugs only ?
How to disable one of those plugins completely ?? Extract from stacktrace :

Just deactivate all the rules from those tools in your quality profile. See http://docs.codehaus.org/display/SONAR/Quality+Profiles

If you want to disable Findbugs for all projects, you could remove that plugin. See http://docs.codehaus.org/display/SONAR/Update+Center or remove it manually from SONARQUBE_HOME/extensions/plugins and restart your server.
