    I was just looking at the JDK on my Mac with Mac OS X 10.7.3 and it looks like I have different versions of the JDK around.
    That's what I have

    Why do I find JDK under two different JavaVirtualMachines folders ? And why are there 2 different JDK under /Library/Java/JavaVirtualMachines ? I'm really confused. How can I check to which version I'm pointing ? Should I remove, and if yes what and how, redundant JDKs ?

    "java -version" will give you the info you are looking for:

    java -version
    java version "1.6.0_29"
    Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-11D50)
    Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02-402, mixed mode)
