Java inherits handle of "modules" file to sub-processes

A DESCRIPTION OF THE PROBLEM :
The JavaVM opens a handle to the file "lib/modules" and sets its inherit attribute to true. As the java.lang.ProcessBuilder also executes new processes with the inherit flag set to true, this handle is inherited to subprocesses. See http://hg.openjdk.java.net/jdk10/sandbox/jdk/file/94d5e1b00394/src/java.base/windows/native/libjava/ProcessImpl_md.c
So subprocesses are not able to modify/delete this file.
My usecase: From a hostapp I want to execute a Updater-App with a separate java installation and then let the Updater install a new hostapp version. Therefore I also need to replace the java binaries of the standalone hostapp.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
You need two java installations (first one must be Java10)
- Create a simple app that runs an infinite loop (App2)
- Create another app (App1) that executes App2 with java.lang.ProcessBuilder and then exits. Use the second VM to execute the app.
- Execute App1 in the first VM
- Use a tool like ProcessHacker to find all open handles of the running App2
-> You will see that there is an open handle to the file "modules" of the Java10 installation



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The JavaVM should not open inherited handles on files. Also ProcessBuilder should not inherit handles to subprocesses.
ACTUAL -
The JavaVM opens inherited handles on the file "lib/modules". ProcessBuilder inherits handles to subprocesses.

FREQUENCY : always
