I decided to try the latest Eclipse integration build, and the following exception ocurred to me on both I20100225-1936 and I20100302-0800 Cocoa-64 builds. This was after upgrading from 3.6M5, which worked fine. eclipse.buildId=I20100225-1936 java.version=1.6.0_17 java.vendor=Apple Inc.

Well in the 2 workspaces I've been able to reproduce this on, I have several hundred projects checked out (about 220 in one, 400 in the other), but what's common between them is that I have about 5 projects in each that have a platform filter on them that don't match the platform I'm on. ie Platform filter is (& (osgi.os=win32) (osgi.arch=x86)) when I'm on Mac OS. I did a little experimenting, used the Target Platform State view to look up the projects with invalid platform filters and closed them all. Upon restarting I no longer ran into the CME. When I reopened the projects and the workspace kicked off a rebuild, it failed with a separate error: Error Thu Mar 04 18:26:43 PST 2010 Errors running builder 'Plug-in Manifest Builder' on project 'com.tasktop.microsoft.outlook.ui'. java.lang.NullPointerException at org.eclipse.pde.internal.core.builders.ExtensionsErrorReporter.validateInternalExtensionAttribute(ExtensionsErrorReporter.java:215) at org.eclipse.pde.internal.core.builders.ExtensionsErrorReporter.validateElement(ExtensionsErrorReporter.java:188) at org.eclipse.pde.internal.core.builders.ExtensionsErrorReporter.validateExtension(ExtensionsErrorReporter.java:109) at org.eclipse.pde.internal.core.builders.ExtensionsErrorReporter.validateContent(ExtensionsErrorReporter.java:74) at org.eclipse.pde.internal.core.builders.ManifestConsistencyChecker.validateFiles(ManifestConsistencyChecker.java:298) at org.eclipse.pde.internal.core.builders.ManifestConsistencyChecker.validateProject(ManifestConsistencyChecker.java:223) at org.eclipse.pde.internal.core.builders.ManifestConsistencyChecker.build(ManifestConsistencyChecker.java:157) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:627) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:170) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:201) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:253) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:256) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:309) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:341) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:140) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:238) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) When I restarted with these projects open again I saw the same CME once more.

The platform filter seems to be just a coincidence, though it did help me narrow down the culprit. One of these projects has an Eclipse-BuddyPolicy manifest entry with no value after it. Manifest doesn't complain about it, but deleting the entry makes the CME disappear.
This looks like a dup of bug 305429.
