Bug 336036

Comment 1 Boris Bokowski 2011-02-02 02:01:19 EST

Andrew, do you know which projects require 1.6 currently? Do they still compile when we target them to 1.5?

Comment 2 Prakash Rangaraj 2011-02-02 02:55:50 EST

From the log, at least 4 of the bundles "need" 1.6:

org.osgi.framework.BundleException: The bundle "org.eclipse.orion.server.user.securestorage_0.1.0.v20110128-1437 [65]" could not be resolved. Reason: Missing Constraint: Bundle-RequiredExecutionEnvironment: JavaSE-1.6

These are mostly authentication and user service bundles. I'll change EE to 1.5 for them.

Comment 4 Szymon Brandys 2011-02-02 10:17:21 EST

I fixed the Orion bundles. However there non-Orion bundles with 1.6 EE set:
- nekohtml
- openid4java
- org.apache.solr.client.solrj
- org.apache.solr.common
- org.apache.solr.core

The first two are in org.eclipse.orion.server/dependencies. We bundleized nekohtml and openid4java some time ago and set the EE to 1.6. I think we should just modify the manifest and rebuild the jars. Both work fine with EE 1.5.

The three others are taken from Orion and they have EE set to 1.6. I'm not sure what we can do about it.

org.apache.solr.* 1.3.0 on Orbit have EE 1.5. I'm not sure if 1.3.0 is fine for us.

And why do we care about Java 5? It's not even a reference platform for Eclipse 3.7, and end of life for Java 5 was over a year ago:

I would actually like to move up to a *newer* Solr at some point to use their new auto-completion support.

Comment 7 Andrew Niefer 2011-02-02 10:53:18 EST

See bug 334598, org.eclipse.orion.server.servlets does contain some 1.6 code, this can be easily fixed to target 1.5.  At the time it was simpler to just use 1.6 since we already had a number of bundles at that level.

Comment 8 Szymon Brandys 2011-02-02 11:43:02 EST

org.apache.solt.* bundles version 1.4.0 do use Java 1.6 API e.g.

import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLStreamConstants;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamReader;

So if we want to run on 1.5, we should have dependencies to org.apache.solt.* 1.3.0. 

Mentioned apache bundles are required by org.eclipse.orion.server.search, so I'm moving the bug to John now.

Comment 9 John Arthorne 2011-02-03 12:35:54 EST

We don't plan to support anything earlier than Java 6. Get a modern VM.
