The commit 5f87c67#diff-b9260ff138b656777898127d2fe03f02%C2%A0changes propertyName handling from StringUtils.uncapitalize(name) to Introspector.decapitalize(name), and it cause exception when the attribue name contain two uppercase letters at beginning.

Example:

 

public interface InebQuestionnaireQuestionRepository extends CrudRepository<InebQuestionnaireQuestionEntity, InebQuestionnaireQuestionEntityPk> {
    List<InebQuestionnaireQuestionEntity> findByTypeAndVCodeOrderByQCodeAsc(String type, String vCode);	
    List<InebQuestionnaireQuestionEntity> findByTypeAndVCodeAndStrategyCodeOrderByQCodeAsc(String type, String vCode, String strategyCode);
}

will cause exception:

The same code fragment works fine on spring boot 1.5.13.RELEASE (spring-data-commons-1.3.12.RELEASE)

The attribue in entity class is :

 

@Id
@Column(name = "Q_CODE")
private String qCode;
