TypeBinding.getDeclaredMethods() return different (more) content with Javac compared to ECJ

[mickaelistria]

For ArrayList TypeBinding.getDeclaredMethods() return different (more) content with Javac compared to ECJ. ECJ returns only 36 methods, while Javac return 60~. A noticeable example, leading to failure of LambdaExpressionsFixCore.testConvertToLambda12 with Javac, is that ECJ doesn't return a binding for the (package visible) removeIf(Predicate, int, int) method, while Javac does.
