Unit test by package broken?

Hello, 

I just upgraded to :

IntelliJ IDEA 2017.2.3
Build #IU-172.3968.16, built on August 21, 2017
Licensed to Brice LEPORINI
Subscription is active until April 10, 2018
JRE: 1.8.0_152-release-915-b11 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Mac OS X 10.10.5

and I run an existing test suite (by package) and it fails because of a network issue:

java.net.SocketException: SOCKS: Connection refused

Process finished with exit code 254
Empty test suite.
