Description Sergei Vorobyov

Java 11 feature.

public class Lambda20 {
    public static void main(String[] args) {
        Arrays.stream(args)
                .filter((var x) -> x.isEmpty()) // Resolution of x.isEmpty() method invocation failed.
                .forEach(System.out::println);
    }
}

The resolveMethodBinding() of the MethodInvocation node returns null.

JDK 11.0.2 compiler compiles the code without errors.

I need this fix in form of Eclipse JDT jar files. Where I can get modules of the 2019-03 release? Thanks.

Download the 2019-03 release? ;p

There's plenty of channels on which JDT is released.

If you need ecj via maven just use the proper dependency to get this:
  http://repo1.maven.org/maven2/org/eclipse/jdt/ecj/3.17.0/ecj-3.17.0.jar 

Here's a list of Eclipse update sites hosting the stuff:

etc.pp.
