repro:
1) create a fresh Java Project
2) create a source directory call it "src"
3) drop the attached source under "src" 
4) should result in the NPE.

Thanks Theodora, your patch is right.

Simpler testcase: 2 files X.java & Y.java, compile X and Y on command line, X being first. Needs to be in 1.5 mode, with diagnostic for missing @Deprecated annotation enabled.

public class X {
	void foo(Y y) {
		y.initialize(null, null, null);
	}
}
public class Y {
	/**
	 * @deprecated
	 */
	public void initialize(Zork z, String s) {
	}

	public void initialize(Zork z, String s, Thread t) {
	}
}
