JdbcLeakPrevention (Apache Tomcat 9.0.36 API Documentation)

org.apache.catalina.loader

## Class JdbcLeakPrevention

- java.lang.Object
- - org.apache.catalina.loader.JdbcLeakPrevention

-     public class JdbcLeakPrevention
      extends Object

  This class is loaded by `WebappClassLoaderBase` to enable it to deregister JDBC drivers forgotten by the web application. There are some classloading hacks involved - see `WebappClassLoaderBase.clearReferences()` for details - but the short version is do not just create a new instance of this class with the new keyword. Since this class is loaded by `WebappClassLoaderBase`, it cannot refer to any internal Tomcat classes as that will cause the security manager to complain.
