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)
s.checkRead(fdObj);
fd = fdObj;
}
Note that SecurityException is unchecked, so it does nto need to be
declared in the throws clause.
