Subject [jira] [Resolved] (ARIES-1755) IllegalArgumentException on weaving
Date Wed, 31 Oct 2018 13:37:01 GMT

     [ https://issues.apache.org/jira/browse/ARIES-1755?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Raymond Augé resolved ARIES-1755.
---------------------------------
    Resolution: Cannot Reproduce
      Assignee: Raymond Augé

I tested against the latest SpiFly 1.1-SNAPSHOT (currently staged for release) and I could
not reproduce. I only made 2 small changes:
 # I set the maven-bundle-version to latest (4.1.0)
 # I set the version of the snapshot spifly static tool

> On weaving a jar that contains a utility loading class like this (this example is an
enum, but the same happens if it's a class, anonymous inner class, etc.):
> {code:java}
> public enum Loader {
>     LOADER;
>     public <S> S load(Class<S> type) {
>         Iterator<S> services = ServiceLoader.load(type).iterator();
>         return services.hasNext() ? services.next() : null;
>     }
> }
> {code}
> The weaving throws this exception:
> {noformat}
> java.lang.IllegalArgumentException: value null
