IntelliJ IDEA tells me “Error:java: Compilation failed: internal java compiler error idea”

Question

When I compile a Java project using IntelliJ IDEA, it gives me the following output (and error):

Information:Eclipse compiler 4.6.2 was used to compile java          


        

Answer 1

In my case, using Java 11, I had:

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

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

 public List 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.
