Are you sure you have the java **development kit**? As it says, it needs not the default usual Java you get from Oracle’s website, but the developer kit thing.

Try installing this:

I suggest you to check if JDK was installed correctly or not. This way we will know if it’s Processing acting up, or you didn’t install it correctly.  
This random thing I found on the internet should help you with this:

Hmm. Does anyone know if Processing 1.x had an external Java dependency?

For some reason I had thought it bundled everything it needed.

What OS are you working with? Can you share the link where you downloaded Processing 1.5 from?
