OutOfMemoryError during test execution - maven

Question

I'm trying to run unit and intergartion tests for jee wildfly application. During tests execution i'm getting stack overflow. I tried to increase memory but wihout success. In my opinion it looks like oom during package creation but i'm not sure.
Can you help? I want also generate jacoco coverage.
I'm using wildfly 10.

Still problem:
Hi, i see that increasing memory don't fix the problem. Insufficient memory was not the reason of the problems. Now i need 6GB RAM and i have 47% of code coverage. So if memory will increase lineary i will need 12GB of free RAM to test my 40MB(with libraries and pictures) app. I think that there is something wrong with that. It looks like memory leak.
Is it normal to have such big memory consumption in arquillian + jacoco configuration?
