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)
HOTSWAP AGENT: 16:47:26.300 RELOAD (org.hotswap.agent.plugin.jvm.AnonymousClassPatchPlugin)
I have integrated OpenJDK Hotswap and pointed wildfly JAVA_HOME to this. My eclipse IDE has connected to wildfly using remote debug. I have modified java file but change are not reflecting in the server. Any idea what is wrong here? I am struck with this issue. Any help will be appreciated.
is the modified .class file deployed to server? Are you following http://hotswapagent.org/mydoc_setup_intellij_idea.html ?
Hi all!
I have problems to have a working DCEVM + HotwapAgent on JBOSS EAP 7.2 Docker Container setup.
Chosen setup:
- Gradle multi project
- Defined
hotswap-agent.propertieswithextraClasspathto build/classes (via docker mount) on subprojectssrc/main/resources.
I managed to launch the container only with disabling JBossModules plugin.
HotSwap Agent doesn't recognise changes during remote debug hot swapping.
If i enable JBossModules plugin i get this error during app server start:
HOTSWAP AGENT: 08:55:11.139 INFO (org.hotswap.agent.HotswapAgent) - Loading Hotswap agent {1.4.1} - unlimited runtime class redefinition.

As I remember there is problem at windows with watching file changes at directory outside docker container, if you have linux, you should not have problem with it
Thank you Vladimir,
i will now check the instructions from https://github.com/HotswapProjects/hotswap-docklands.
I want run this setup on OSX, do you know if this setup works there?

btw, did you try last dcevm :) ?
