Weird java.net.SocketException Permission Denied connect error when running Groovy in Intellij IDEA

When running a VERY simple URL grab script from within IntelliJ IDEA, I get:

java.net.SocketException: Permission denied: connect

but when I run it from the Groovy Console, it works just fine.

Here is the full script:

def data = new URL("http://wisc.edu").getText()

and here is the full console output from IntelliJ:

Process finished with exit code 1

I have absolutely no idea what is causing the problem, but my guess is that it's something IDEA is doing when it runs the groovy code that keeps it from being able to access the network.

Has anyone else experienced this? Does anyone know of a workaround?

Solution

  • There is a known bug in JDK 1.7 related to IPv6.

    Adding -Djava.net.preferIPv4Stack=true in VM Options should fix the problem.
