Jersey and Java 8 (Lambda expression)

Question

I use Jersey version 1.18.1 (com.sun.jersey), Spring and Java 8. If I put a Java 8 Lambda expression in a REST service, it crashes. If I remove the lambda expression, it works.

@Service
@Path("/hello")
public class Hello {

    @GET
    public String hello() {
        new ArrayList<String>().stream().filter((str) -> str.length() > 0);
        return "hello";
    }

}

I use com.sun.jersey (1.18.1 version).

Full stacktrace:

SEVERE: Allocate exception for servlet jersey-serlvet java.lang.ArrayIndexOutOfBoundsException: 52264
    at jersey.repackaged.org.objectweb.asm.ClassReader.readClass(ClassReader.java:1976)

    at com.sun.jersey.core.util.Closing.f(Closing.java:71)

Please tell me how to fix it.

@Malahov so you tried with Jersey 2.7+ and got the same issue? — assylias, Jun 16 '14 at 07:42
For com.sun.jersey last version 1.18.1. I didn't try org.glassfish.jersey. — Malahov, Jun 16 '14 at 10:04
any luck ? Ican't make it work with the latest jersey dependencies — Seb, Jun 03 '16 at 14:52

Jersey 1.18 is not compatible with java 8. They added java 8 compatibility since 1.19.

If you take a look at the Jersey 1.19 release notes, you can see the introduced the jdk8 support.

https://github.com/jersey/jersey-1.x/releases/tag/1.19

Quoting the 1.19 tag:

Thanks to @cowwoc you're able to run Jersey 1.x applications on JDK8

To fix this you have to upgrade Jersey to 1.19 or downgrade java 8 to 7.

We had similar problem. Also com.sun.jersey in use.

After migration to the newest version (19.1) all works. So simply please upgrade to the newest version.
