It is true that GIN is kind of unmaintained. There has been some internal patches but nobody bothered moving the project out of Google code and export those due to initial overhead.
Bu regardless, right now GIN uses reflection with a ClassLoader hack to access types. And at least some code visible by GIN will be compiled by JDT (e.g. super-source code, classes generated by other generators etc.) so it will see java8 byte code (hence the error). I don't see a practical way to make GIN work in a JDK 7 environment. If there are other similar generators, they will not work in JDK7 as well but I don't believe there are many like that.
