Using SimiDroid out of memory

[SoarLife]

I try to analyse 1400+(about 5G size)apk's Similarities,and I download the android-platform from https://github.com/lilicoding/android-platforms as cf recommented.

And simidroid-config.xml :

<SimiDroid>
	<AndroidJarsPath>android-platforms</AndroidJarsPath>
    <Plugin name="METHOD">
        <LibrarySetPath>res/libs91.txt</LibrarySetPath>
    </Plugin>
</SimiDroid>

I run the SimiDroid.jar from the download unzip file:

/artefacts/SimiDroid.jar

and my apks is in apks/

java -jar SimiDroid.jar apks/

after hours,I get this exception:
