Tabula-Py not working - Called Process Error - non-zero exit status 1

Question

I'm trying to use Tabula-py to do some data scraping from PDF's however I can't get quite it to work. I'm running this in my Jupyter notebook (on a Mac):

from tabula import read_pdf
df = read_pdf("/Users/jamesozden/Downloads/pdfminer-20140328/samples/simple1.pdf")

And I'm getting this error:

Error: 
---------------------------------------------------------------------------

So I read some previous questions about having java installed, which I do. I also made sure I added the path to my bash profile (I'm relatively new to this so I'm not sure if I've done it correctly). Here is the line I added to my bash.profile in case anyone wants to make sure it's okay, which I got from using which java :

export PATH="$HOME/usr/bin/java/bin:$PATH"

Any help would be much appreciated, thank you!

I managed to sort it myself! Turns out even though I had downloaded the updated version of Java, version 1.6 was the one being used (this one seen using java -version). I used homebrew to upgrade to java 8 and now it is working fine.
