Failed to leave the current IsolateThread context and to detach the current thread. (code 12) with Micronaut and LDAP

[ilopmar]

Describe the issue

We have in Micronaut a test application for Micronaut Security and LDAP. To make it work as a native image we've used the tracing agent to add the following reflection configuration that we've already included in Micronaut Security. The test application works as a native image using Java 11:

[
  {
    "name":"com.sun.jndi.ldap.LdapCtxFactory",
    "methods":[{"name":"<init>","parameterTypes":[] }]
  }
]

For Java 8 this doesn't work. Using the tracing agent again we've discovered a missing reflection configuration that I've added to the test application described below:

[
  {
    "name":"com.sun.jndi.ldap.VersionHelper12",
    "methods":[{"name":"<init>","parameterTypes":[] }]
  }
]

Steps to reproduce the issue

• git clone https://github.com/micronaut-graal-tests/micronaut-security-ldap-graal
• cd micronaut-security-ldap-graal
• git checkout jdk8-issue
• Use GraalVM for Java 8
• ./build-native-image.sh
• ./build/native-image/security-ldap
• curl -s -X POST -H 'Content-Type:application/json' -d '{"username":"euler","password":"password"}' localhost:8080/login

The native image process finishes with the error:

Fatal error: Failed to leave the current IsolateThread context and to detach the current thread. (code 12)

Describe GraalVM and your environment:

• GraalVM version: 21.0.0.2 Java 8. Also tried with master branch ac8a4ff
• JDK major version: 8
• OS: Linux Mint 20.1
• Architecture: AMD64

Hello @ilopmar, can you please if this issue is still present in the latest versions of GraalVM JDK8 and micronaut?

[ilopmar]

Hi @fernando-valdez, I'm no longer part of the Micronaut team. Maybe @sdelamo can take a look at it.

[sdelamo]

@fernando-valdez have you tried with Micronaut Framework 4 and Java 17 and Graal 17.0.8-graal?

Maybe error code 12 is from here?

    @Description("Some exception is not caught.") //
    public static final int UNCAUGHT_EXCEPTION = 12;

A bit funny description 😅

A few 1BRC contestants ran into this, but it seems not always reproducible. Seeing it right now for this entry for instance: gunnarmorling/1brc#575.
