Problem using maven surefire plugin in "pertest" fork mode in Windows environment

[Davide Zerbetto <ze...@gmail.com>]

Hi!
I have a problem using maven surefire plugin in "pertest" fork mode in
Windows environment (in Linux it works properly).
Tests use DBUnit 2.1: the db is a HSQLDB file.
Here below a fragment of my pom.xml:
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <configuration>
            <forkMode>pertest</forkMode>
            <systemProperties>
                    ....
            </systemProperties>
            <excludes>
                   ....
            </excludes>
            <testFailureIgnore>true</testFailureIgnore>
          </configuration>
      </plugin>
I launch the command "mvn surefire-report:report" or "mvn test" from command
line.
I got an exception like "the database is already in use by another process"
and all (or nearly all) tests fail.
Can anyone help me?
Thank you
