Why am I getting a NullPointerException when connecting to MySQL from Java?

Can't connect to MySQL from Java: NullPointerException in MySQL driver connection logic

Issue:

When attempting to establish a connection to a MySQL database from Java code, the DriverManager.getConnection() method consistently fails with a NullPointerException originating from within the MySQL driver's connection logic.

Troubleshooting:

• Confirm Compatibility: Ensure that the version of the MySQL driver used matches the version of the MySQL server.

• Update Driver: If using an older driver version, consider updating to the latest version.
  To download the latest version, visit https://mvnrepository.com/artifact/mysql/mysql-connector-java.
  Alternatively, update the pom.xml file by adding the following dependency:

  <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.11</version>
  </dependency>

• Address MySQL Server Change: Newer MySQL server versions have introduced changes related to character sets and collations. These changes may cause compatibility issues with older driver versions. If using MySQL 8.0.1 or later, ensure that the driver version is 5.1.41 or higher, as this fix was introduced in that version.
