Hi Michael,
Michael McMahon said the following on 04/13/11 21:33:
This issue occurs on some versions of Windows since we switched compiler
to VC 2010. The new C runtime library requires the "SystemRoot" environment
variable to be set, when launching sub-processes via Runtime.exec() or
ProcessBuilder.
The problem occurs in instances where the environment is specified by
the caller,
rather than simply inheriting (or inheriting and adding to) the
environment of the parent process.
The change is simple enough. We just check for the presence of
"SystemRoot" in the
child process's environment, and set it if it's not there. No change
will be visible
to the parent process. But, to avoid ambiguity, we'd like to make the
change explicit with a small spec. change.
Spec change seems fine to me.

Is it possible to watch for the SystemRoot entry while iterating through
at line 322 (ProcessEnvironment.java) instead of doing the iterative
search before-hand? Or even doing the sort first and then a
binary-search? Maybe the environment on windows is small enough that
this isn't an issue?
Also what if the parent process doesn't have SystemRoot set in its
environment? Does the child just get a 'null' entry?
Cheers,
David
Thanks,
Michael.
