Writing to file in JUnit test case? Not working?

Question

I have a singleton class called InstantLogger that internally uses a PrintWriter to write to file. It is very basic, has startLogger(String filename), log(String msg), and stopLogger(). startLogger just creates file, log write to file, and stopLogger closes file.
When I use this class outside of the JUnit test suite it works fine.
As soon as I use it in a JUnit test it does not write to file. It creates the file (this happens in the TestSuite), but will not write anything to it (when log is called from TestCase). I put a System.out in the log function and I see that, but still nothing writing to file. And I will say it again, it does work in non TestCase scenarios so I know it works.
Is there something that could be preventing me from writing to file in JUnit TestCase? Could this be a Singleton Issue?
Thanks,

Your code is wrong. You're assuming something that isn't correct. You're also making the assumption that just because it "works" in another context that it's right in all contexts. The two aren't the same, be it configuration or something else.
Singleton? That GoF pattern has been voted off the island. Didn't you hear?
