------------------------------
> @AutoImplement for method with type parameter(s)
> ------------------------------------------------
>
> Key: GROOVY-10552
> URL: https://issues.apache.org/jira/browse/GROOVY-10552
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.5.15, 3.0.10, 4.0.1
> Environment: Ubuntu 20.04 / Groovy 4.0.1 / OpenJDK 8
> Reporter: Peter Giles
> Assignee: Eric Milles
> Priority: Major
> Fix For: 5.0.0-alpha-1, 2.5.17, 3.0.11, 4.0.2
>
>
> I have tried a few permutations of Groovy versions and Java versions, and I
> can't get this to work with anything I've tried that is above Groovy version
> 2.5.12:
> {code:java}
> import groovy.transform.AutoImplement
> public class AutoImplementExample {
> public static void main(String ... args) {
> def c = new DummyConnection()
> c.commit()
> }
> }
> @AutoImplement
> class DummyConnection implements java.sql.Connection {}
> // Name this file AutoImplementExample.groovy and try to compile and run{code}
>
> For example, with Groovy 4.0.1, JDK 8, and my GROOVY_HOME, PATH, and
> JAVA_HOME set up as instructed in the installation page for Groovy:
> {noformat}
> ~/groovy-autoimplement$ groovy -version
> Groovy Version: 4.0.1 JVM: 1.8.0_312 Vendor: Private Build OS: Linux
> ~/groovy-autoimplement$ java -version
> openjdk version "1.8.0_312"
> OpenJDK Runtime Environment (build 1.8.0_312-8u312-b07-0ubuntu1~20.04-b07)
> OpenJDK 64-Bit Server VM (build 25.312-b07, mixed mode)
> ~/groovy-autoimplement$ groovyc ./AutoImplementExample.groovy
> ~/groovy-autoimplement$ groovy AutoImplementExample
> Caught: java.lang.NullPointerException

> This stacktrace looks similar to the error I see with other Groovy versions
> and JDK 8. The trace looks slightly longer with JDK 11, but everything from
> AutoImplementExample.groovy:5 and above looks the same, right down to the
> line numbers.
> I've also run this with *java* (after compiling with {*}groovyc{*}) to make
> sure there is nothing funny going on when running directly with *groovy* that
> could be sullying the results. That's a bit messier to run in that I have to
> construct a long classpath for all the groovy jars, and for that effort I
> just get a longer stack trace with the same bits at the top.
