[SUREFIRE-1573] PpidChecker inherits and blocks resources from tests while checking if the forked VM is still alive

• Type: Bug

• Environment: Windows, our tests create temporary files using native-code (std::fstream) and remove or rename them using boost::filesystem. Java 1.8.

Description

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-)

ERROR_SHARING_VIOLATION

32 (0x20)

The process cannot access the file because it is being used by another process.

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.
