also seen before NPE:
java: compiler message file broken: key=compiler.misc.msg.bug arguments=11.0.17, {1}, {2}, {3}, {4}, {5}, {6}, {7}


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile attached source code

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
compiles
ACTUAL -
NPE in compiler

---------- BEGIN SOURCE ----------

class CompNpeLambdaReproIndep {
interface IntProcedure {
boolean execute(int a);
}

static class Outer {
void foreach(IntProcedure p) {
}
}

interface RunnableWithException<E extends Exception> {
void run() throws E;
}

static <E extends Exception> void propagateAndRun( RunnableWithException<E> rwe) {
}

class Nested {
void method2() {
Outer map = new Outer();
map.foreach(intParam -> {
propagateAndRun(() -> {
System.out.println("reference outer param " + intParam);
});
return true;
});
}
}
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Extract innermost lambda into a method

FREQUENCY : always
