JdbcLeakPrevention (Apache Tomcat 10.1.55 API Documentation)
Description: declaration: package: org.apache.catalina.loader, class: JdbcLeakPrevention

# 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.
