It’s because of Eclipse is on 32-bits JVM and your environment is pointing to Java JVM 64-bits, you can check your default JVM via Java -version.

To solve this, you can install another 32-bits JVM and let’s eclipse point it or passing in your eclipse.ini with following JVM parameter:


The argument -d32 tells eclipse to pick the right JVM to use. I did that so that I do not need to install another JVM in my PC.
