constructor - Java UNIXProcess not visible in Eclipse? -

i tried use unixprocess.class, eclipse keeps warning me unixprocess not visible.

the code simple:

java.lang.unixprocess declared default visibility means cannot seen classes outside of package java.lang.*. use processbuilder or runtime.exec(), instead, create valid process object.
