Hi all! I get the following exception during testng ant task:

   [testng] Exception in thread "main" java.lang.OutOfMemoryError: PermGen space

This seems to be a PermGen space issue and I don't believe is related to
the actual code.
You can try increasing the permgen space for your JVM running the tests
with these settings:
-XX:PermSize=256m -XX:MaxPermSize=256m

The default is 128 MB if I remember correctly.

Let us know if you need further help

If you use Eclipse, this can be configured in two ways:

1. edit Eclipse.ini passing this parameters or
2. in JVM properties (Window >> Preferences >> Installed JREs >> Edit) - Set this in Default VM Parameters.

I don't use Eclipse. I run tests through Ant.

[Cosmin Marginean]

In that case:

• ANT_OPTS - command-line arguments that should be passed to the JVM. For example, you can define system properties or set the maximum Java heap size here.

(from here: http://ant.apache.org/manual/running.html )

That worked. Thank you very much!
