Piping text from some programs doesn't work well

[DeflatedPickle]

• Example 1: echo;
  • Test
  • Fix

>echo Hello | perl flamingo.pl
          ___________
         /           \
 |       | Hello
         \________,  /
                   \/
...

Here, we can see the pipe that should be on the far right ends up at the start, possibly?

• Example 2: java;
  • Test
  • Fix

>java | perl flamingo.pl
Usage: java [-options] class [args...]
           ...
                    _
                   / \
                   \/
                   /
...

Here, the text is printed before the flamingo command. Possibly due to the java command not being able to pipe?
