Consider the following:15
If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.16
If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).17

As I see the JAR file name was changed from mchange-commons-java-0.2.19.jar to c3p0-0.9.5.5.jar.
Expected file path:
xxxxxxxxxx1
C:\Users\thomas\.m2\repository\com\mchange\c3p0\0.9.5.5\mchange-commons-java-0.2.19.jarFound file path:
xxxxxxxxxx1
C:\Users\thomas\.m2\repository\com\mchange\c3p0\0.9.5.5\c3p0-0.9.5.5.jarHints:
- it looks like bug caused by changes against detected vulnerabilities in Mchange Commons Java » 0.2.19 (check this link)
- if you use hibernate-c3p0, check latest versions and site notification:
Note: This artifact was moved to: org.hibernate.orm » hibernate-c3p0 » 6.0.0.CR2

Solution
You can try to:
- Upgrade
hibernate-c3p0
https://mvnrepository.com/artifact/org.hibernate/hibernate-c3p0 - or: do not use:
xxxxxxxxxx1<dependency>2<groupId>org.hibernate</groupId>3<artifactId>hibernate-c3p0</artifactId>4<version><!-- used version here ... --></version>5<scope>compile</scope>6</dependency>
