Ideally all applications would quote correctly and avoid implicit 
execution of cmd.exe but there is a lot of existing code that doesn't. 
Some of the Oracle release notes and articles on this topic are here:

https://blogs.oracle.com/thejavatutorials/entry/changes_to_runtime_exec_problems

The javadoc isn't really the place for this amount of highly Windows 
specific detail. There may be a case of referencing implementation 
specific documentation, we have several areas where such references 
could be useful to supplement the API docs.
