I solved this issue by increasing the default value(700) of Build process heap size on IntelliJ’s compiler settings.

I changed my compiler to Eclipse and run my project. Afterwards changed back to Javac and problem solved. I don’t know exact problem but it can help who is looking for solution.

In my case, using Java 11, I had:

 public List<String> foo() {
   ...
   return response.readEntity(new GenericType<List<String>>() {});

and Intellij suggested I should use <> instead of GenericType<List<String>>, as such:

 public List<String> foo() {
   ...
   return response.readEntity(new GenericType<>() {});

I did that in four functions and the project stopped compiling with an internal compiler error, reverted and it compiled again. Looks like a bug with type inference.
