Subject [jira] [Commented] (LUCENE-3927) allow running trunk tests with IBM JRE
Date Tue, 27 Mar 2012 09:01:34 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13239327#comment-13239327
] 

Robert Muir commented on LUCENE-3927:
-------------------------------------

{code}
if (!(Codec.forName("Lucene3x") instanceof PreFlexRWCodec)) {
        System.err.println("ERROR: Your VM's java.util.ServiceLoader implementation is buggy"+
          " and does not respect classpath order, please report this to the vendor.");
{code}

I think this could be confusing to people using Sun JVMs, but just with the wrong
classpath? There is currently an assert for this:
{code}
assert (codec instanceof PreFlexRWCodec) : "fix your classpath to have tests-framework.jar
before lucene-core.jar";
{code}

So I think we should just be careful about the warning to not confuse (maybe check Constants.JRE_VENDOR
to 
make sure we send the correct message?)

> This is currently not possible because of how the SPI loader works,
> we cannot simulate Lucene3x codec with PreFlexRWCodec.
> But we should still allow basic testing (even though we cannot test preflex).
> After hacking around the issue, I get interesting fails with this JRE so I think its
worth it.
