I have Spring 1.5.21.RELEASE spring boot project and I am not able to initialize the Spring Boot Datasoruce org.apache.commons.dbcp2.BasicDataSource. When application start-up I get the following exception. I have tried and try to debug but I am not able to figure which incompatibility causing this issue. I am using Java 8.

 Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Dbcp2.class]: Initialization of bean failed; nested exception is java.lang.reflect.MalformedParameterizedTypeException

I had to use a newer version of commons-pool2 from 2.5.4 to 2.6.2.

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-pool2 -->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.6.2</version>
</dependency>
