      Description

      I had this Java code:
      javax.​persistence.Query query = entityManager....;
      List<?> lastKeyIds = query.getResultList();
      if (!lastKeyIds.isEmpty()) ...

      and tried to replace element type from "?" (in "List<?>") by pasting "BigDecimal" from clipboard. When I tried to repeat the same action, it didn't fail.

      NetBeans stacktrace:
