Subject [jira] [Commented] (KARAF-957) Cannot specify systemPackage options when using karaf.testing.Helper
Date Mon, 24 Oct 2011 04:24:32 GMT

    [ https://issues.apache.org/jira/browse/KARAF-957?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13133822#comment-13133822

Raman Gupta commented on KARAF-957:

Well, it doesn't seem to work anyway when using systemPackages(...), probably because of a
bug in the ancient version of Pax-Exam that is being used by the Karaf tooling.

However, the fix for this issue will still be useful since a work-around for the pax-exam
bug is to use:


but that does not work unless this issue is resolved, since Pax-Exam adds the new system property
before the VMOptions defined by karaf, and therefore the Karaf empty value for the same property
overrides it.

The work-around to THAT is to use this little chunk of code instead of Helper.getDefaultOptions()
directly (this assumes the value for org.osgi.framework.system.packages.extra is empty, which
it is by default):

        Option[] karafHelperOptions = Helper.getDefaultOptions();
        List<Option> karafOptions = new ArrayList<Option>(karafHelperOptions.length);

        for(Option o : karafHelperOptions) {
            if(o instanceof VMOption) {
                String oldVmOption = ((VMOption)o).getOption();
                StringBuilder builder = new StringBuilder(oldVmOption.length());
                final String extraStr = "-Dorg.osgi.framework.system.packages.extra=";
                final int startExtra = oldVmOption.indexOf(extraStr);
                    .append(oldVmOption.substring(0, startExtra))
                    .append(oldVmOption.substring(startExtra + extraStr.length() + 1));
                VMOption newVmOption = new VMOption(builder.toString());
            } else {

> When using the karaf.testing.Helper, it pre-sets the "org.osgi.framework.system.packages.extra"
property to an empty value. Then, when using pax-exam systemPackages(...) option to add system
packages to the list, it does not work since org.osgi.framework.system.packages.extra already
exists in the option list.
