Looks fine, just re-check the FIS/FOS constructors as original check file==null was for the SM usage.

src/java.base/share/classes/java/io/FileInputStream.java line 136:

I assume (old) L133-139 can be replaced with `String name = file.getPath()`, the explicit check that name is null goes away with the SM check.

src/java.base/share/classes/java/io/FileOutputStream.java line 205:

Same comment as the FOS constructor.
