Error in Decompiler class when processing classes with java 8 stream mechanism

[faustocarva]

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:

Code to test the class:

    @Test 
    public void decompileStreamSupport() {
        try {
            File classFile = new File("./target/test-classes/samples/StreamSupportSample.class");           
            assertNotNull(classFile);

            IValueFactory vf = ValueFactory.getInstance();
            Decompiler decompiler = new Decompiler(vf);
            IConstructor c = decompiler.decompile(new FileInputStream(classFile), null);

            assertNotNull(c);
        }
        catch(Exception e) {
            e.printStackTrace();
            fail(e.getLocalizedMessage());
        }
    }

@rbonifacio this one is already done, corret? Can I close it?
