BPEL Editor throws SWTException on startup because color registry is not initialized
------------------------------------------------------------------------------------

                 Key: JBIDE-7724
                 URL: https://jira.jboss.org/browse/JBIDE-7724
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: bpel
    Affects Versions: 3.2.0.Beta2
            Reporter: Robert (Bob) Brodt
            Assignee: Robert (Bob) Brodt
            Priority: Blocker
             Fix For: 3.2.0.Beta2


This is a threading issue: during startup, the color and image registries are initialized in the CommonUIPlugin, but two (or more) threads are using the color registry when the editor is started; one of these threads initiates the registry creation and is interrupted by the other thread which attempts to use it before it has been properly initialized.

The result is that an SWT exception is thrown. Stack trace follows:
