I just tried. It finished with 1.38G ram.
How much memory do you have?
Try adding -Xmx4G to the command line and let me know how it goes?

[fatalioerror]

3Q,
I have only 4G physical memory (actually 3.7G)
so
export JAVA_OPTS="-Xms512m -Xmx3G"
I will try!

[fatalioerror]

add JAVA_OPTS did not take effect.
I try

java -Xmx3G -jar target/pysonar-2.0-SNAPSHOT.jar /usr/lib/python2.7 ./html

it success!

[Yin Wang]

Just to be curious, how much memory does it show in the end of the output? What kind of machine you have? JDK version?

[fatalioerror]

2.67G.
