How to get junit on classpath?

[Nick Williams]

DOPE! I totally goofed on this one. I didn't read the whole stack trace. If I had, I would have seen this:

    [stacktrace]
Caused by: java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing
    [stacktrace]
Caused by: java.lang.ClassNotFoundException: org.hamcrest.SelfDescribing
    [stacktrace]

JUnit started requiring Hamcrest as of JUnit 4.4, but through JUnit 4.8.2 Hamcrest was bundled in the JUnit JAR (which is a no-no). Starting with JUnit 4.9 (including my 4.11) Hamcrest is no longer bundled (as it should be) and you have to download/attach Hamcrest separately.

Skeptical about my chances, I put hamcrest.jar in $JT_HOME/lib assuming it wouldn't work, and it didn't. I wasn't surprised. I downgraded to the JUnit 4.8.2 JAR and it's working now. Jtreg might want to start looking for hamcrest.jar now, too. JUnit 4.8.2 is three years old.

I'm using the Makefile to run tests (that's what the JDK readme says to do, and I don't dare venture away from that lol). Looking at the output, the executed process doesn't include the words "junit" anywhere so Makefile apparently isn't using the jtreg startup script.
