Exception in thread “main” java.lang.UnsupportedClassVersionError: a (Unsupporte d major.minor version 51.0)
I have been using Eclipse with jre 1.7.x and jdk 1.7.x before and I had to downgrade to 1.6x.
The way that I downgraded was to uninstall all the 1.7 related from my computer and install 1.6 again.
Now, when I try to debug, I am getting
`java.lang.UnsupportedClassVersionError: MyClass: Unsupported major.minor version 51.0`
I checked the version of JRE and JDK that used to compiled, both of them are 1.6.
Can anyone help with this?
Your runtime version is different from compile time version.
Make sure
JAVA_HOME
variables etc., to make sure compile and runtime both pointing to same version.
