Please, could you explain?
method
public static void patch(final CtClass ctClass is called from HotswapTransformer.transform, it adds $$ha$clinit method to class. Then the class is reloaded by dcevm, so the actual class reinitialization must be called in callback using scheduler.scheduleCommand. Class is now redefined after 150ms since the class can have be proxied by dynamic proxies (com.sun.proxy, etc...).
please can someone help me? https://stackoverflow.com/questions/52840428/alfresco-hotswapagent-extraclass
How to use hotswapper plugin withouy using IDE. I'm starting wildfly server with hotswapagent and altjvm options. I have a exploded war file with hotswap-agent.properties file with watchresources and extraclasspath pointing to the class folder. Whenever the classes files are getting changes ,the changes are not hotreloaded. Am i missing any configurations?
I have checked the documentation..But still classes are not getting reloaded. Look at https://stackoverflow.com/questions/55687372/hotswapper-plugin-is-not-reloading-classes-in-web-project for description
LOGGER=trace
extraClasspath=/home/user/HotSwapTest/target/classes
webappDir=/home/user/HotSwapTest/src/main/webapp
watchResources=/home/user/HotSwapTest/target/classes
autoHotswap=true
autoHotswap.port=8000
extraClasspath=/home/user/HotSwapTest/target/classes
webappDir=/home/user/HotSwapTest/src/main/webapp
watchResources=/home/user/HotSwapTest/target/classes
autoHotswap=true
autoHotswap.port=8000
but you can use some old dcevm, probably from original source
New HA user here. Can HA only be used to hotswap dependency classes (in webapp) when their classes folder is added to extraClasspath configuration? Or is it possible for HA to find all hotswap-agent.properties files on the entire classpath and find dependency hotswap classes via their respective extraClasspath properties?
i ve managed to hotswap my web application , but changes i ve made beign applied a bit late
about every 10 secs , not as soon as i save the file , anyone knows how to solve this
thanks btw ^^
Hi again,
on this page : https://github.com/TravaOpenJDK/trava-jdk-11-dcevm it is written that I can build my own release
Small question about that : do I need something special to make a build based on 11.0.4 ?
I also saw that the travis yaml file has references to jdk10, any reason for that ? Or is this travis file not up to date ?
Thanks in advance for your help.

@mryvz after saving process, java build new classes and reload them this takes a bit.
On the project i'm working building new classes takes also 10-15 secondes
you need to wait after the IDE told you that the classes where reloaed or do you try to refresh the webpage directly after pressing save without waiting that everything was reloaded?

If this works well, you're likely going to have a flood of Grails developers looking to avoid being forced to use jRebel just to remain productive since Grails 4 uses a later version of spring boot so no longer has the magic behind hot-swapping of classes which was one of the attractions of the framework in the first place.

i dont think its compile issue , im using compile on save option in netbeans. Save configuration with tomcat working almost insta ,
as you sugested i refresh page without waiting classes updated message but nothing :( ,
in my opinion wildfly (thorntail) has internal classpath something like search deamon which has 10 secs period

Hi, i have done successful integration of Hotswap Agent(used openjdk11) with wildfly. I have connected wildfly with remote debugger from eclipse. Code changes are getting reflefcted only for methods. If i add a new class it is not getting swapped to the wildfly, i am getting java.lang.NoClassDefFoundError. Can anyone help me how i can fix this?
Hello
I have strange behavior with the agent. I have SpringBoot + Vaadin + tomcat setup.
For my test I have a simple thread that output string in a console.
When I change the value of the output string, I have to reload the page to have the updated srting , but the previous string is still outputed. Actually I can see that 2 Threads are now present like if the hotswap agent did a duplication of the updated code.

Thread t = new Thread(new Runnable() {
@Override
public void run() {
while(true) {
try {
System.err.println("within the loop 7");
Thread.sleep(2000);
if(grid.isAttached() && grid.isVisible() ) {
updateLastActiveRuns();
}
} catch (InterruptedException e1) {
}
}
}
});
t.start();
So basically each time I update the output string, I have a new version of the code that is spawned, concurrently to previous versions
When I save updated java code I see
HOTSWAP AGENT: 16:47:26.300 RELOAD (org.hotswap.agent.plugin.jvm.AnonymousClassPatchPlugin)
