I have sometimes problems to run my Apps in the debugger. The debugger can't load it's class. Looking at the error log i found the following Exception before the ClassNotFoundException of the debugger. Strange is that after a project rebuild everything works fine again ???!!! Thanx Bjoern 1 Log Entry: java.lang.ClassCircularityError: org/eclipse/jdt/core/JavaModelException at org.eclipse.jdt.launching.JavaRuntime.<clinit>(JavaRuntime.java:116) at

Related to bug 27401. If we avoid triggering classpath resolutions (for activating background indexer) during startup, then this one defect will be resolved as well.
Deferred to M5. Changes are quite big and too close to M4. Need more testing.
Removed all index consistency checks from JDT Core startup. Released changes to persisently keep track of saved & consistent index files... any request to an inconsistent index adds a rebuildAll job to the queue.
*** Bug 29009 has been marked as a duplicate of this bug. ***
Verified.
