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.
