Hi,

I have this method:

    public void testListMetadata() {
        try {
            ListMetadataQuery query = new ListMetadataQuery();
            query.setType("Package");
            double asOfVersion = 26.0;
            // Assuming that the SOAP binding has already been established.
            FileProperties[] lmr = sfd.getMetaConnection().listMetadata(
                    new ListMetadataQuery[]{query}, asOfVersion);
            if (lmr != null) {
                for (FileProperties n : lmr) {
                    System.out.println("Component fullName: " + n.getFullName());
                    System.out.println("Component type: " + n.getType());
                }
            }
        } catch (ConnectionException ce) {
            ce.printStackTrace();
        }
    }

 I assume it should return for me list of the installed packages.

Is it correct assumption?

But I have an error:

com.sforce.ws.SoapFaultException: UNKNOWN_EXCEPTION: An unexpected error occurred. Please include this ErrorId if you contact support: 1379208547-383 (1089039615)

	at com.sforce.ws.transport.SoapConnection.send(SoapConnection.java:98)
	at com.sforce.soap.metadata.MetadataConnection.listMetadata(MetadataConnection.java:160)

I've debugged inside and saw that at transport level I have http error 500 Internal Server Error

 How to solve it?

Where to create ticket for SF team to investigate this issue?
