spilling long logs does not make your post easier to read. Use a pastebin site instead (pastebin.com or paste.ubuntu.com) to post your log.

 

you also have java 7, the original, without updates whatsoever.

That's not the reason why your server crashes, but it's also very bad to leave the very engine Minecraft needs to run on outdated.

 

Update your java 7 to java 7u71

or

Uninstall it

Restart your PC

Install Java 7u71 https://www.java.com/en/download/manual_java7.jsp

 

Do not get Java 8u25, that one will break Forge and make modpacks unplayable
