java.lang.NoSuchMethodError: org.springframework.beans.MutablePropertyValues.add(Ljava/lang/String;Ljava/lang/Object;)Lorg/springframework/beans/MutablePropertyValues;
After a little bit of googling I saw that the root cause is the fact that we use old versions in some Spring components next to new ones. I removed the old ones from pom.xml and everything's fixed.
