             Summary: PpidChecker inherits and blocks resources from tests while checking if the forked VM is still alive
                 Key: SUREFIRE-1573
                 URL: https://issues.apache.org/jira/browse/SUREFIRE-1573
             Project: Maven Surefire
          Issue Type: Bug
    Affects Versions: 2.22.0
         Environment: Windows, our tests create temporary files using native-code (std::fstream) and remove or rename them using boost::filesystem.
            Reporter: Marcus Ackermann


On Windows, the PpidChecker executes wmic through cmd by starting a new process. Java calls {{CreateProcess}} with the flag {{bInheritHandles=TRUE}}.

When I create a temporary file in a test, it happens that this file can neither be removed nor deleted. The error code is the following (from https://docs.microsoft.com/en-us/windows/desktop/debug/system-error-codes--0-499-)
{code:java}
ERROR_SHARING_VIOLATION

32 (0x20)

The process cannot access the file because it is being used by another process.{code}
I found out that this sharing violation is due to the fact that the process started from PpidChecker also owns the file inherited from the test process.

This seems to be a side-effect of the new monitoring mechanism for the forked VM introduced in 2.20.1 with SUREFIRE-1302.
