      A DESCRIPTION OF THE PROBLEM :
      the following 5 lines of code cause a StackOverflowError in javac:

      import java.util.Arrays;

      public class Foo {
      final Object o = Arrays.stream(new String[]{}).map(x -> x)+"\n";
      }

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Create a file called Foo.java

      2. Paste these 5 lines of code into Foo.java:

      import java.util.Arrays;

      public class Foo {
      final Object o = Arrays.stream(new String[]{}).map(x -> x)+"\n";
      }

      3. run: javac Foo.java
