Why doesn't my Eclipse start in El Capitan?

I have been working in Eclipse for a while and recently I had to change java_home for some other application. Since then my Eclipse doesn't start. I have followed all the solutions posted to questions similar to this but no use. These are some details regarding the problem.

java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.92-b14, mixed mode)

javac -version
javac 1.8.0_92

When I try to open Eclipse through terminal via open Eclipse.app/ , I get prompt to look at the following log at /Eclipse.app/Contents/Eclipse/configuration/1465758949259.log

In the previous questions, many have suggested to remove few files in the .metadata folder in workspace. I have tried completely removing the workspace itself but still Eclipse won't start. I have also tried ./eclipse -clean. Any guide would be really helpful.
