Ok, looks jython behaves different with respect to pipes... you  can try
this.

import subprocess
px = subprocess.Popen("tasklist",stdout=subprocess.PIPE)
py = subprocess.Popen("findstr notepad",stdin=px.stdout,stdout=subprocess.PIPE)
px.stdout.close()
out = py.communicate()[0]
py.returncode
#assuming notepad is not running, this will return 1


#now open notepad
px = subprocess.Popen("tasklist",stdout=subprocess.PIPE)
py = subprocess.Popen("findstr notepad",stdin=px.stdout,stdout=subprocess.PIPE)
px.stdout.close()
out = py.communicate()[0]
py.returncode
#this returns zero.
