Error in Decompiler class when processing classes with java 8 stream mechanism #8
Description
Hi, the decompile method in Decompiler class is generating an error when processing classes with java stream mechanism.
Below the code to reproduce the error:
package samples;
import java.util.Arrays;
import java.util.List;
public class StreamSupportSample {
public static void main(String[] args) {
List<String> myList = Arrays.asList("a1", "a2", "b1", "c2", "c1");
myList.stream().filter(s -> s.startsWith("c")).map(String::toUpperCase).sorted().forEach(System.out::println);
}
}
Error message:

IValueFactory vf = ValueFactory.getInstance();
Decompiler decompiler = new Decompiler(vf);
