I am trying to debug a problem wherein a colleague keeps getting the dreaded error
Unsupported major.minor version 52.0
when trying to load project in Eclipse. I’m trying to understand this and none of it makes sense. There is a project that was built with 1.7 JRE library. I fixed that, getting rid of all mentions of “1.7” in all the settings files. But whenever I refresh the project or reimport the project , it goes back to 1.7. The default workspace JRE is jdk-1.8. what is going on here?
