Java AWS handler separator is incorrect

[couryrr]

Does this need an issue on the GitHub repo to work on? I can dedicate sometime to getting this implemented. I also opened another one about defaults which will be in the same area I can work on in this.

Update Lamdba deploy default to match a new Lambda instance

In the code of travis there is default_memory_size and default_timeout. These are set to 128 (mb) and 3 (sec) respectively. A newly created lambda on AWS defaults to 512 (mb) and 15 (sec). It would be recommended to match the providers defaults.
