[jira] [Commented] (GROOVY-11578) Services loaded via the service loader not working in (some) OSGi contexts for Groovy 4+

Paul King commented on GROOVY-11578:
------------------------------------

I also added an additional test to my Karaf spike (tests that the 
groovy-datetime module is working, it's not a service but extension methods 
could disappear if there were classloader issues with that module):
{code:java}
    @Test
    public void testExecGroovyDateTimeCommand() throws Exception {
        String resultNoArgs = executeCommand("groovy:exec \""
                + "import java.time.LocalTime\n"
                + "println LocalTime.of(23, 59).format('HH:mm')\"");
        assertContains("23:59", resultNoArgs);
    }
{code}
It and the other Groovy tests pass with spifly reverted back to 1.2.4. 
Reverting the version is obviously a workaround.

> This is related to GROOVY-11570 and GROOVY-11571 but it seems worthwhile 
> having an issue that is just about getting the services working again.
> Current steps to reproduce:
> * clone the apache/karaf repo
> * change groovy versions: codehaus=>apache, 3.0.24=>4.0.26
> * add an additional test to GroovyTest (see below) to exercise service loader 
> related functionality
> * run "mvn test" in the itests directory
> Additional test:
> {code}
> @Test
> public void testExecGroovyJsonCommand() throws Exception {
