Changes not applied with version 1.3.0 for Grails 4 & 5

[purpleraven]

For grails 4 I'm using version 1.2.8 of spring-loaded. It works well, except reloading of methods with @transactional
grails/grails-core#12630 (comment)

But during upgrade to grails 5.2.6 for one of my applications I got a jvm crash during application startup with for some GORM classes
grails/grails-core#11649 (comment)

With spring-loaded 1.3.0 (and also with springloaded-1.3.0.BUILD-20210404.024037-2.jar provided by @Dirk-27 grails/grails-core#11649 (comment)) application starting up well, but changes in a code not applied during reload:
I see recompilation in the log, but behaviour of application not changed.
For example I have added to a controller action logs, but don't see it during action execution (throwing exception too)

I have seen same problems with grails 4 and spring-loaded 1.3.0 before. Also I have checked this new version of library with another three grails 5* applications and see a same problem. Working well, but no result =)

Java corretto-1.8.0_362

build.gradle

configurations {
  agent // for hot reload
  developmentOnly
  runtimeClasspath {
    extendsFrom developmentOnly
  }
}

dependencies {
   agent files('lib/springloaded-1.3.0.BUILD-20210404.024037-2.jar')//"org.springframework:springloaded:1.3.0.RELEASE"
//  developmentOnly("org.springframework.boot:spring-boot-devtools")
....
}

application.groovy

...
spring.devtools.restart.enabled = false
...

and repeat it in application.yml (just for test)

spring:
    devtools:
        restart:
            enabled: false

What I'm duing wrong??

Test application. test-grails5.zip

After startup by run-app with open http://localhost:8080/test/index and see OK
Change TestController render "Ok" to render "NO"

Refresh page, see

But in browser the same responce Ok

Sorry, we don't tried grails 5 yet. And in grails 4 everything works well. We use openjdk version "1.8.0-292".

@Dirk-27 I have the same problem with grails 4.

test-grails4.zip

Probably I'm doing something wrong

[Dirk-27]

Yes: you don't use the jar I mentioned but added a dependency 'agent...'. Then you get the wrong springloaded version. I get your test-xxx running by

1. comment the agent line in dependency section
2. add the jar line: jvmArgs('-javaagent:libs/springloaded-1.3.0.BUILD-20210404.024037-2.jar', ...

Download the file (exactly this one: springloaded-1.3.0.BUILD-20210404.024037-2.jar) and save it to (new folder) libs in your project before.

Update: java 11 has been used. Works with grails 4

@Dirk-27

I have added agent to bootRun

bootRun {
    ignoreExitValue true
    jvmArgs(
        '-Dspring.output.ansi.enabled=always', 
        '-noverify', 
        '-XX:TieredStopAtLevel=1',
        '-Xmx1024m',
        '-javaagent:libs/springloaded-1.3.0.BUILD-20210404.024037-2.jar')
    sourceResources sourceSets.main
    String springProfilesActive = 'spring.profiles.active'
    systemProperty springProfilesActive, System.getProperty(springProfilesActive)
}

But I'm getting error

Here your sources work on my computer. When a 'grails clean' didn't work for you my only idea is the different JDK you use.

[purpleraven]

@Dirk-27 everithing works with grails 5 too.

do I need the agent line in the configuration?

configurations {
    agent // for hot reload
    developmentOnly
    runtimeClasspath {
        extendsFrom developmentOnly
    }
}

What differrence between released 1.3.0 and springloaded-1.3.0.BUILD-20210404.024037-2.jar ?

After tersing I will ask grails team to update documentation.

[Dirk-27]

The both lines I changed (commented agent line and added in the jvmargs) was all have changed. And I don't know what the different in the jar is, but this is the last build and it works. (- I'm out of office for today)
