Switching versions of Java on OSX
http://stackoverflow.com/questions/21964709/how-to-change-default-java-version
First run
/usr/libexec/java_home -V
Pick the version you want to be the default (1.6.0_65-b14-462 for arguments sake) then:
export JAVA_HOME=`/usr/libexec/java_home -v 1.6.0_65-b14-462`

my vim config file :)
" To start vim without using this .vimrc file, use:
" vim -u NORC
"
" To start vim without loading any .vimrc or plugins, use:
" vim -u NONE
"
" Use vim settings, rather then vi settings (much better!)
" This must be first, because it changes other options as a side effect.
