This creates the interesting situation, that the JVM verifies stricter

implementation even documents this as a workaround if you want to
avoid the validation.)
Would it make sense to officially describe this in the exec(String[]),
that you can specify the path to a bat/cmd file as the first argument
and do not need to use the cmd /c?
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:

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.
