		<fail>ERROR: No test environment set up.

You need to set up a test environment, which consists of a version of javac, and a JRE runtime classpath ('rt.jar').
Eventually, this environment concept will be extended to also include an ecj and/or eclipse to test against.

You can let this ant script set them up for you:

* ant setupJavaOpenJDK6TestEnvironment
* ant setupJavaOpenJDK7TestEnvironment
* ant setupJavaOracle7TestEnvironment
* ant setupJavaOracle8TestEnvironment

These will set up test environments based on OpenJDK6 and OpenJDK7, and download all required files automatically. This will be a relatively large download. You can switch by running this command again; the downloads are cached so switching is fast.

You can also create your own by writing a 'testenvironment.properties' file. The relevant properties are:

* test.location.javac = /path/to/javac6.jar
* test.location.bootclasspath = /path/to/rt.jar
