-vm in eclipse.ini is not considered during the eclipse launch in mac os x

I was facing this issue, I have multiple Java versions installed in my Mac system and I wanted to change my eclipse default Java version.

I have configured -vm parameter in eclipse.ini file in mac os x, but some how this parameter didn't take effect.
-vm
Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin/java

To resolve this issue, I have followed the below link.

What worked for me is, configuring libjvm.dylib path in the eclipse.ini file and info.plist file.

eclipse.ini
-------------
-vm
Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/server/libjvm.dylib

info.plist
----------
<key>Eclipse</key>
<array>
<string>-vm</string>
<string>/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/server/libjvm.dylib</string>
</array>

Add above entry in the last.

info.plist file can be found in below location:
Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents

eclipse.ini -vm option

-vm argument is useful for passing virtual machine to the eclipse.ini. Mostly this will be used where your system configured Java is different and you wanted to pass different version of java version to the eclipse.

Please follow below link from eclipse
https://wiki.eclipse.org/Eclipse.ini

Example: In windows

-vm
C:\Java\JDK\1.6\bin\javaw.exe

Example: In Mac OS X

 -vm
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java

This argument should always before the -vmargs arguments and -vm and parameter value should specified in different lines.

In Mac OS X, some times this is not working. Even though we have specified in the eclipse.ini file, eclipse launcher is always taking the different jvm.
