regression with surefire 2.12 plugin and SecurityManager

We are running all our tests using a special security manager that restricts IO in tests. There is a regression when running these tests with the 2.12 plugin compared to the 2.11 plugin:

How to reproduce:

1) git clone git@github.com:NessComputing/components-ness-pg.git
2) mvn clean compile test-compile
3) Run the tests with the 2.11 plugin:

mvn -Dtest=TestPostgresUtils org.apache.maven.plugins:maven-surefire-plugin:2.11:test
