Problems with testing

[bartekleon]

Hello again dear Nico and Simondel,
Since again I have some time to help with your project I started with cloning installing and running your code. And there is a problem,

It crashed 3 times in a row (first time probably coz I haven't used 'npm run build')
the second one was of course with timeout in stryker\stryker\packages\webpack-transpiler\test\unit\compiler\WebpackCompiler.spec.js,
but the last one is super strange:

ChildProcessProxy
@stryker-mutator/core:        should throw an OutOfMemoryError if the process went out-of-memory:

I think this has to do with wct only supporting java 8 and below. You're probably on a newer version. I kind of have a love-hate relationship with WCT, as you can see with the amount of issues reported by me.

Apparently, [email protected] should support Java 8+.

We're happy to accept PR's for this issue 👍

Wouw!! I had this issue yesterday as wel. It was a problem with Stryker! It occurred on Windows with Node12.

I fixed it in #1635. If not, please open a new issue. Thanks!
