Subject Re: [jira] Commented: (HARMONY-71) java.net.URLConnection.setUseCaches throws unspecified IllegalAccessError
Date Thu, 16 Feb 2006 14:00:20 GMT
I would rather that you just opened a new JIRA issue for that as it
doesn't relate to the original problem.

FYI there is a local server incoming in the HARMONY-57 contribution, so
don't spend any time on it, see:
<HARMONY-57>\Harmony\Harmony_Tests\src\test\java\tests\support\Support_HttpServer.java

Regards,
Tim

a local server in it. Could you reopen this JIRA?
