Description ANIRBAN CHAKRABORTY CLA 2013-04-08 05:28:43 EDT 
public interface Foo { 
	int run1(int s1, int s2);
	static int x2 = 0;
}

interface Foo1 {
	Foo run2(int argFoo1);
}

interface X extends Foo{
	
    static int x1 = 2;
    static Foo f = (x5, x6) -> x5;
    static Foo1 f1 = af1 -> (a1,b1) -> {int uniqueName = 4; return uniqueName;};
    		
}

eclipse compiler clean, reference commandline compiler crash and seemingly total breakdown of code-assist inside the curly braces in the above multilevel lambda.

Thanks

Code assist works fine in this example having been fixed by other recent
resolved bugzilla(s). However I noticed that this test case triggers an
NPE if the semicolon in the return statement is removed. 

Fix and tests for that problem released here: http://git.eclipse.org/c/jdt/eclipse.jdt.core.git/commit/?h=BETA_JAVA8&id=31f5d8c3352dfd40743cbafcdc19d9f5e7640d54
