The page 5 is empty.
I found the EmptyStackException at the ContentParser.parseText.
The PDF has a mailformed line which is though the content parser off:
f 1 0 0 1 BT 40.79 233.75 Tm (CURRENT CHARGES) Tj
There is a sudo random "BT" token added to the line above and is causing our content parser some grief.
I"ll apply a patch that still tries to get the correct text transform matrix, otherwise "CURRENT CHARGES" will be written in the incorrect spot.l

Closing issue. Updated parser with a slightly different approach then above. The fix insures that the identity matrix is created and is back filled with numbers popped of the stack until the stack is empty.

Can you post a sample file that demonstrates this issue? I'm concerned they might be a different type of parsing error occurring here.
