Build fails out of the gate

Hello, I am trying to do `mvn clean install` but some tests fail due to some files being used by other parts of the system while a test is to remove that file. It's affecting Windows computers, but builds fine on Linux. Here is the log:

```

Run `mvn clean install` and inspect `se.kth.castor.jdbl.util.MyFileUtilsTest`, especially `deleteUnusedClasses` at line 42 and `restoreFiles` at line 51. Reproduce the file-locking failure on Windows and compare the test-resource cleanup with the Linux behavior. Done means the tests complete successfully on Windows without breaking the existing Linux build.
