[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-9147) A lot of Java Model Exceptions when updating project pom

[Viacheslav Kabanovich (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-9147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12608971#comment-12608971 ] 

Viacheslav Kabanovich commented on JBIDE-9147:
----------------------------------------------

Now I see what happens. The problem appeared when building of CDI extensions was included into CDI build.
Previously, steps were as follows:
1. Create working copy of context.
2. Update class path (which removes from working copy objects loaded from removed paths)
3. Load objects to working copy of context.

With CDI extensions, steps changed as follows:
1. Update class path (which removes from working copy objects loaded from removed paths)
2. Update extensions based on new class path in current context.
3. Create working copy of context (including working copies of contexts for extensions).
4. Load objects to working copy of context.

Here item 1, as before, cleans a working copy 'created on the fly' but that copy is discarded and replaced by new one created in item 3 - with all paths.

Now, proposed patch modifies steps as follows.

1. Update class path (store the set of removed paths).
2. Update extensions based on new class path in current context.
3. Create working copy of context (including working copies of contexts for extensions).
4. Remove from working copy stored paths.
5. Load objects to working copy of context.

I think it is safe to merge to M2.
