tomcat-reload-and memory leaks

Using TOMCAT8, Project PermSize is 64MB and project Lib size is 33m

Reloadable= "true" in the project,

If you update the class file but do not restart Tomcat then there will be a memory leak of Perm Space error after a period of time.

The probable cause is

1.mysql JDBC

2.ThreadLocal variables

3. Log Frame

4.WebAppClassLoader

Using Jmap to export memory snapshots The Eclipse Memory Analyser analysis found that JDBC and WebappClassLoader took up the most classes, and there were two WebappClassLoader objects.

A temporary workaround is to stop using reload and increase the permsize size
