An Odd Interaction Between Ant, JUnit, and IntelliJ

Question

I must be losing my mind. Things that I used to know in my sleep are failing me these days.
I'm running JUnit 3.8.1 and Ant 1.6 in IntelliJ 4.5 on Windoze XP and Sun's JDK 1.4.2. (Enough acronyms?)
I've got an Ant build.xml that I've flogged on a bunch of projects at my last employer. It's nice and generic and shaken down nicely. It has a compile step that's followed by a dependent <junit> task, which runs all the JUnit TestCases I've accumulated, generates XML reports, deploys the app, and then generates javadocs. I've used it many times on the command line and in Eclipse 3.0.
My latest employer has sprung for IntelliJ 4.5, which I like VERY much. After learning Eclipse it's been no problem to figure out what IntelliJ is doing for me.
My problems start when I try to use my lovely build.xml in IntelliJ. It compiles all my code fine, but when it tries to run the JUnit task it always comes back with ClassNotFoundException when it tries to load the TestCase. That means CLASSPATH, right? I'm setting CLASSPATH in the build.xml. I can look at the properties that JUnit says it has when it runs the test, and I can see the full path to the TestCase in the java.class.path property. I've used the <echo> task to print out the converted CLASSPATH before running JUnit, and I can see the TestCase in the CLASSPATH then, too.
If I open a command shell and run the junit.textui.TestRunner by hand, adding the appropriate JARs using the -classpath option, everything is perfect.
What the heck am I doing wrong? Anybody else running JUnit in IntelliJ via Ant?
