 While ECJ supports the same interfaces as Javac that are used to call the compiler from this library, [eclipse-jdt/eclipse.jdt.core#1153](https://github.com/eclipse-jdt/eclipse.jdt.core/issues/1153) means we will not get functional Java 11 support going forwards. 
 
-A number of issues were found while developing  [ascopes/java-compiler-testing#163](https://github.com/ascopes/java-compiler-testing/issues/163) with ECJ which prevents many features such as JPMS support from working correctly. Since it is unlikely these issues will be addressed in the near future, support for ECJ has been shelved.
