I've developed this same problem tonight. Game ran fine the last time I played (12 hours ago). No new software downloaded in the mean time.
I click "Play" from the website.
Tonight when I clicked "Play", it downloaded some sort of game update following my usual Java security prompt. After that, I've been having crashes every few seconds. Memory usage on the jp2launcher goes up to around 1.5GB and then crashes.
I've downloaded the latest Java update for both 32-bit and 64-bit, and downloaded the latest drivers for my video card. Restarted computer. Makes no difference. Problem still happening.
Specs: Win7 Ultimate 64-bit, Intel i5-2500K processor, 16 GB RAM, nVidia GeForce GTX 750 Ti with 2 GB dedicated memory. Also have 8 GB shared system memory available.
