After much chopping, I have finally narrowed it down to a single source file, and no external dependencies (other than starting Windows' cmd.exe process) : https://github.com/bruno-medeiros/Scratchpad/blob/jvm-processio-issue/jvm_process_bug/src/JVMProcessBug.java
In this final form, I am now able to replicated the bug in my machine on many different runs of the program even beyond the first one after booting. But it doesn't occur every time, only about two thirds the time. Tried running it again with JVM 8 several times but never got it to reproduce there. Maybe it really isn't present in JVM 8, only 7. Hopefully this should be enough for JVM developers to replicate it. -- Bruno Medeiros https://twitter.com/brunodomedeiros
