The same project runs with APM 1.8 Javaclient but with 1.9.0 the JVM crashes without any information from program

I'm sorry to hear that. On which Java version, vendor and OS does that happen?

3

java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

With Windows 10 host

4

But it is the same with OpenJDK 12.0.1 and langugage level 12

5

Any crash reports from the JVM? Look out for hs_err_pid<pid>.log in the current directory.

6

nope :rage:

7

but you should easily reproduce it.
Create a project from springinitzlr site and add apm agent version 1.9 :wink:

8

Did you make any progress on this issue ?

Sorry for the radio silence. I was on vacation last week. I'll try to reproduce at home where I have a Win 10 desktop PC. My inbox is kinda exploding but I'll try to investigate this asap.

Did you try run this on ubuntu?
On ubuntu application started success:

nindzya@pc:/opt/nindzya$ java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

Pitty that's not a solution for me.

The company have a Microsoft infrastructure :rage:

I could finally reproduce it. It's currently a restriction of the emulated attach on Windows (see also https://github.com/raphw/byte-buddy/issues/723). It crashes the VM if the agent arguments are too long.

A workaround for this is to use system properties for the configuration:

public static void main(String[] args) {
    System.setProperty("elastic.apm.service_name", "simulation");
    System.setProperty("elastic.apm.application_packages", "eu.amova,com.siemag,pas.core");
    System.setProperty("elastic.apm.stack_trace_limit", "0");
    System.setProperty("elastic.apm.span_frames_min_duration", "0ms");
    System.setProperty("elastic.apm.disable_instrumentations", "elasticsearch-restclient,concurrent,executor,jax-rs,jax-ws,jdbc,scheduled");
    System.setProperty("elastic.apm.server_urls", apm_server_urls);
    ElasticApmAttacher.attach();
    SpringApplication.run(DemoApplication.class, args);
}
