Steps & Code to Reproduce

i dont not the step

Hello, thanks for reporting this, however this is not a core issue, It is a JNI issue in the Java SDK.
In particular, I think this is the offending code:

JNIEnv* JniUtils::get_env(bool attach_if_needed)
{
    REALM_ASSERT_DEBUG(s_instance);

    JNIEnv* env;
    if (s_instance->m_vm->GetEnv(reinterpret_cast<void**>(&env), s_instance->m_vm_version) != JNI_OK) {
        if (attach_if_needed) {
            jint ret = s_instance->m_vm->AttachCurrentThread(&env, nullptr);
            REALM_ASSERT_RELEASE(ret == JNI_OK);
        }
        else {
            REALM_ASSERT_RELEASE(false);
        }
    }

    return env;
}

I am not an expert, but it seems to me that JniUtils::get_env(bool attach_if_needed) was called with attach_if_needed = false.

It is similar to #6987.

How often does it happen? Any particular operation which triggers it?
