SecurityException thrown during test case generation

[jbsiii]

I'm getting a strange error when I generate test cases. If I run the cases from the Junit runner built in to Eclipse, they run fine. But CodePro refuses to execute the tests. Here's the comments it inserted into the test case code:
// An unexpected exception was thrown while executing this test:
// java.lang.SecurityException: Cannot write to files while generating test cases
// at com.instantiations.assist.eclipse.junit.CodeProJUnitSecurityManager.checkWrite(CodeProJUnitSecurityManager.java:79)
// at java.io.FileOutputStream.<init>(FileOutputStream.java:169)
// at java.io.FileOutputStream.<init>(FileOutputStream.java:70)
// at com.jeppesen.EDS.EssentialDeltaSet.setDirs(EssentialDeltaSet.java:37)
// at com.jeppesen.EDS.EssentialDeltaSet.<init>(EssentialDeltaSet.java:28)

Here's the line it's pointing to in the class being tested:
EDSFile = new ZipOutputStream(new FileOutputStream(EDSFileName));

What am I missing?

What version of CodePro, Eclipse and Java are you using?

In order to produce useful assertions, the test code generator attempts to execute the method under test during the test code generation process. But in order to prevent damage to your computer it first installs a security manager that disallows code that tries to access external resources, such as your hard drive.

That comment was produced by the test code generator to let you know that it was unable to produce better (or maybe any) assertions because the security manager threw an exception.

When you use JUnit to execute the tests there is no security manager, so the test runs fine.

What version of CodePro, Eclipse and Java are you using?

Sorry, I forgot to mention that. Using Ganymede, JDK 1.6, and the most recent version of CodePro (evaluation underway).
