I am receiving the following message from my Eclipse compiler, and my project fails to compile....

Internal compiler error: java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.problem.ProblemReporter.missingTypeInMethod(ProblemReporter.java:5075)

I've tried updating Eclipse, restarting eclipse, closing and opening the project, refreshing, cleaning/rebuilding, etc. I'm out of ideas.
