The two lines are:
ModelEntry entry = (ModelEntry) getEntryTable().get(oldID);
IPluginModelBase[] activeModels = entry.getActiveModels();

entry can be null and there is no check for null.

I got this by checking out all these projects:
org.eclipse.jdt.compiler.apt
org.eclipse.jdt.compiler.apt.tests
org.eclipse.jdt.compiler.tool
org.eclipse.jdt.core
org.eclipse.jdt.core.tests.builder
org.eclipse.jdt.core.tests.compiler
org.eclipse.jdt.core.tests.formatter
org.eclipse.jdt.core.tests.model
org.eclipse.jdt.core.tests.performance

and then I deleted all files into each project and I tried to commit them.
Don't worry. I am not doing this in the public CVS repository.
