RFR 9 8055330: (process spec) ProcessBuilder.start and Runtime.exec should throw UnsupportedOperationException ...

[Martin Buchholz]

One reason I keep pouring salt on this tiny wound is that throwing
(unchecked) UOE for system-dependent failures when normally IOE is thrown
is a fundamental design mistake for java and its checked exception design.
I think it violates Josh's Effective Java Item 58: Use checked exceptions
for recoverable conditions and runtime exceptions for programming errors.
I don't think it's worth fixing places in jdk8 where this small mistake was
made, but we can at least stop the incompatible worsening of existing APIs.
