Spring Boot 2.7.8 DataSource 설정 문의

Question

Spring Boot 2.7.7 까지는 이상이 없는데,2.7.8 이랑 2.7.9 에서는 오류가 납니다...설정이 뭔가 바뀌었을까요?혹시 아시는 분 있으신가 해서 문의드립니다.오류 내용[16:46:05:252][main][ERROR][HikariPool:throwPoolInitializationException:594] - HikariPool-1 - Exception during pool initialization. java.util.ConcurrentModificationException: null그외 데이터소스 및 트랜젝션 히카리풀 오류 내용들이 있지만가장 첫번째 뜨는 오류는 위와 같습니다..계속 2.7.7 만 쓰기는 그렇고 바뀐 부분이 있으면 알아둬야 할거 같은데...application-local.propertiesspring.datasource.hikari.driver-class-name&#61;net.sf.log4jdbc.sql.jdbcapi.DriverSpy spring.datasource.hikari.jdbc-url&#61;jdbc:log4jdbc:mariadb://dev.in4in.com:3306/coea_web?useUnicode&#61;true&characterEncoding&#61;utf8 spring.datasource.hikari.username&#61; spring.datasource.hikari.password&#61; spring.datasource.hikari.connection-timeout&#61;4800 spring.datasource.hikari.max-lifetime&#61;26800000 spring.datasource.hikari.connection-test-query&#61;SELECT 1 spring.datasource.hikari.maximum-pool-size&#61;10DatabaseConfig&#64;Configuration &#64;EnableTransactionManagement &#64;MapperScan(basePackages &#61; {&#34;com.infoin.app.**.mapper&#34;}, annotationClass &#61; Mapper.class) public class DatabaseConfig { private static final String MYBATIS_CONFIG_LOCATION &#61; &#34;mybatis/configuration.xml&#34;; private static final String MYBATIS_MAPPER_LOCATION &#61; &#34;classpath:mybatis/mappers/**/*.xml&#34;; &#64;Bean &#64;ConfigurationProperties(prefix &#61; &#34;spring.datasource.hikari&#34;) public HikariConfig hikariConfig() { return new HikariConfig(); } &#64;Bean(name &#61; &#34;datasource&#34;) public DataSource dataSource() { return new HikariDataSource(this.hikariConfig()); } &#64;Bean public PlatformTransactionManager transactionManager(DataSource dataSource) { return new DataSourceTransactionManager(dataSource); } &#64;Bean public SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception { SqlSessionFactoryBean sqlSessionFactory &#61; new SqlSessionFactoryBean(); sqlSessionFactory.setDataSource(dataSource); sqlSessionFactory.setConfigLocation(new ClassPathResource(MYBATIS_CONFIG_LOCATION)); sqlSessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(MYBATIS_MAPPER_LOCATION)); sqlSessionFactory.setVfs(SpringBootVFS.class); return sqlSessionFactory.getObject(); } &#64;Bean public SqlSessionTemplate sqlSessionTemplate(SqlSessionFactory sqlSessionFactory) { return new SqlSessionTemplate(sqlSessionFactory); } }지금까지 잘쓰다가 프로젝트 새로 생성하니까2.7.8 로 생성되어서 JDBC 테스트 해보니 오류 나더라구요.혹시 몰라서 버전 낮췄더니 이상 없구요...근데 또 그사이에 2.7.9 버전도 나왔더라구요.2.7.9 버전에서도 마찬가지로 오류 납니다.두번째 단락 오류org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'coeaFrontApplication': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.annotation.ProxyTransactionManagementConfiguration': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'transactionAspect': Unsatisfied dependency expressed through field 'transactionManager'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'transactionManager' defined in class path resource [com/infoin/config/app/DatabaseConfig.class]: Unsatisfied dependency expressed through method 'transactionManager' parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'datasource' defined in class path resource [com/infoin/config/app/DatabaseConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: null

해당 버전들의 릴리즈를 확인해보시면 MariaDB 및 Mysql 드라이버 업데이트가 포함되어있습니다.해당 의존성 버전을 다운그레이드 해보시는게 좋을 것 같습니다.
