[jbosstools-issues] [JBoss JIRA] (JBIDE-10077) JPA: NPEs when try to create some error markers

[Dmitry Geraskov (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-10077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12650413#comment-12650413 ] 

Dmitry Geraskov commented on JBIDE-10077:
-----------------------------------------

1. Create custom NamingStrategy
2. Add it to console configuration
3. Add throw new UnsupportedOperationException into method columnName
4. Create Entity and add @Column annotation to one of the fields with specified name
5. Build console configuration
6. When project validation is done:
Error marker should appear near column name and your exception in the log with Naming strategy exception message instead of NPE which appeared earlier.

> Earlier we used null as turget object in some places. Probably API changed in the place and null should not be used any more.
