Bug ID: 64527
Summary: JarWarResourceSet gc caused class loading slowly
Product: Tomcat 8
Version: 8.5.39
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: springqi...@gmail.com
Target Milestone: ----
Hi,
I have a spring boot application with embed tomcat, when i deploy my
application(a war package with 329 jar and 227Mb size) to servers, when i first
loading a class by Class.forName, it take several seconds.
I debug some tomcat source code, finally i noticed that when i load a class not
loaded before, it will always run into getArchiveEntries, it will check
archiveEntries is null and load from war file. And i also noticed in
JarWarResourceSet gc method will periodic execution set
archiveEntries=null.Caused class load slowly when archiveEntries=null, because
it will scan all of my war package resources to build a cache.
I'm override JarWarResourceSet let gc method do nothing, it fixed my problem.
But I don’t know if I’m right, so I’m asking here.
tomcat version: 8.5.39
spring boot version: 2.0.9.RELEASE
