Is there a reason, for assuming that the security manager is not
available at this point or is this only some forgotten code that,
by chance, nobody else but me run into?

I agree that it looks wrong. My guess is that the SecurityManager wasn't working correctly at the time the FileInputStream was written so we ended up with some weird code.

In libgcj the implementation is simply:

  public FileInputStream(FileDescriptor fdObj)
    SecurityManager s = System.getSecurityManager();
    if (s != null)
    fd = fdObj;

Note that SecurityException is unchecked, so it does nto need to be declared in the throws clause.
