mongodb fails to delete a temporary file

Using maven dependency:

<dependency>
                <groupId>de.flapdoodle.embed</groupId>
                <artifactId>de.flapdoodle.embed.mongo</artifactId>
                <version>1.50.1</version>
                <exclusions>
                    <exclusion>
                        <groupId>org.apache.commons</groupId>
                        <artifactId>commons-lang3</artifactId>
                    </exclusion>
                    <exclusion>
                        <groupId>org.apache.commons</groupId>
                        <artifactId>commons-compress</artifactId>
                    </exclusion>
                </exclusions>
                <scope>test</scope>
            </dependency>

Within Intellij, if I debug a test and shut the test down prematurely (e.g. at a breakpoint) the temporary file that embedded mongo creates does not get deleted (I guess the shutdown hook never runs):

C:\Users\XXX\AppData\Local\Temp\extract-XXX-extractmongod.exe

Additionally, after installing BitDefender, this seems to happen even if I run a whole run without pausing and killing prematurely. I get the message at the end of the test:

[mongod output] 2016-09-16 13:50:24.716  WARN 13120 --- [      Thread-11] d.f.embed.process.io.file.Files          : could not delete C:\Users\XXX\AppData\Local\Temp\extract-XXX-extractmongod.exe. Will try to delete it again when program exits.

It would be good to have a utility function that I can use to just delete this file at the start of a test.

Faced same issue, following is a work around that can be used. This should be executed before the start of embedded mongo db

    String tempFile = System.getenv("temp") + File.separator + "extract-" + System.getenv("USERNAME") + "-extractmongod";
    String executable;
    if (System.getenv("OS") != null && System.getenv("OS").contains("Windows")) {
        executable = tempFile + ".exe";
    } else {
        executable = tempFile + ".sh";
    }
    Files.deleteIfExists(new File(executable).toPath());
    Files.deleteIfExists(new File(tempFile + ".pid").toPath());

It happens when some failure shuts down mongo or tests with mongo prematurely as @manishpatelUK kindly pointed out. Possible solution: delete this file backing up it beforehand. Worked for me.
