Somebody actually performed a small trade 15x market price.

It's normal you can fulfull trades at any price you like.

Unrelated I'm going to suspend btc deposits for a while pending investigation of some cross credit during the past hours.

Looks like an overkill. All I need is just to load and save raw bytes.
Do we talk about blockchain in December 2014? Smiley
AFAIR minimal jar of HSQLDB is just 1Mb.
Compare to already used Jetty...

15x previous price  Shocked

Quick buy feature that lets to buy bypassing lower ask orders?
I don't know, i can guess exchange is translating order price, not trade price. There are many ask orders that this trade had to bypass.

@ Java gurus:

I'm going to get rid of Serialization that's used to load/save data files. Would it be a good idea to use http://docs.oracle.com/javase/7/docs/api/java/nio/MappedByteBuffer.html? I thinking about mapping the files into the memory and leaving the rest for the OS. If a node is being shut down the OS will dump memory to the disk, right?
Why not use embedded SQL engines like H2 or HSQLDB?

I can no longer connect to my account using local 7875 port running the java client, only possible through 7874 peers port. Why?
Tried httpS ?
Thank you klee, worked out with adding https!

By the way I am stuck at 8786 block for more than 30 minutes Sad

I see block 9118. Delete peers.nxt and catch recent blocks.

Could someone simply explain for a newb how to secure my Nxt application?

- Do NOT run Nxt on a VPS.  Only run Nxt locally.  Even if you connect to your VPS securely via SSH, you are still not safe because all VPSs have backdoors.
- 7874 (tcp) is used for P2P communication, the http web client and API commands.  This is the only port that needs to be open to run Nxt.
- 7875 (tcp) is used for the https web client.
