ADDITIONAL SYSTEM INFORMATION :
Tested on Windows 11 OpenJDK 23 build 27/26

A DESCRIPTION OF THE PROBLEM :
When jshell.exe starts it launches any executable called "test.exe" that is in the Path

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Setup path and verify no version of test.exe is in your path:
set Path=C:\java\jdk-23\bin
test.exe
=> Reports 'test.exe' is not recognized as an internal or external command,
operable program or batch file.
Then setup Path with any executable as test.exe: I just copied Notepad++.exe to a new folder:
> mkdir c:\Temp\abc
> copy "\Program Files\Notepad++\notepad++.exe" c:\Temp\abc
> set Path=C:\java\jdk-23\bin;c:\Temp\abc
> jshell


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Notepad++should not be launched each time I run jshell.exe.
Works as expected in JDK22
ACTUAL -
In JDK23 jshell launches Notepad++ (or whatever was copied as test.exe in the path).

CUSTOMER SUBMITTED WORKAROUND :
Remove all executables called "test.exe" from the Path

FREQUENCY : always
