Build 20020515 In self-hosted workspace, opened JavaProject, lots of errors got discovered into it due to some missing types. In particular, Openable was said to be missing although it was there. After forcing a build, problems were gone. No reproduceable steps, suspecting some concurrency issue closing a buffer under the resolver.
Unable to find truly reproduceable steps, however usually if breaking on error reporting (problem is error) in self-hosting workspace and quickly opening many editors, the problem will usually occur at some point. Actually, found several areas where concurrency could cause grief. Reconciling with errors can lead to populate the Java model concurrently, and the following areas are problematic in multi-threaded mode: - JavaElement#getRawInfo isn't synchronized on JavaModelManager - senders of JavaElement#getInfo must be protected, since element opening first adds the info in the cache (e.g. isOpen) - Namelookup#findType is sharing its type and package requestors amongst concurrent invocations - Namelookup#workingCopies cache isn't thread safe. If computing a hierarchy while reconciling, reconciliation might see unwanted working copies (before they get initialized).
Protected all the above scenarii, and cannot reproduce issue anymore.
Fixed
