+/**
+ * Reproduction for issue b/143628636.
+ *
+ * <p>There are a lot of conditions that need to be in place to trigger this issue. The root issue
+ * is resolution incorrectly pruning out a valid candidate. However, mostly code will not even get
+ * to that place as a single target is typically found prior to it, and then, if the incorrect
+ * pruning of the lookup targets takes place, that needs to further cause invalid call site
+ * information to be propagated, which in turn will cause inlining to inline a method where it
+ * should not. It is exceedingly unlikely that this test will continue to be a regression test as
+ * any one of the above aspects could and likely will be changed in the code base.
