quarkus - 图像堆中不允许...的实例，因为此类应在图像运行时初始化

Question

我正在运行一个简单的 Java 应用程序(只是一个 REST 端点，一个“Hello”响应 - 正是 Quarkus maven 原型(prototype)生成的示例，没有修改)具有以下堆栈:

• Quarkus(微文件)
• JDK 1.8 热点 1.8.0_231-b11
• GraalVM 19.3.0(原生图像)
• MacOS Catalina

这是第一个错误(虽然它似乎不是主要问题):

[code-with-quarkus-1.0.0-SNAPSHOT-runner:1868]        setup:   8,524.65 ms

真正的问题(我认为)在这里:

Error: com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: No instances of java.net.Inet4Address are allowed in the image heap as this class should be initialized at image runtime. To see how this object got instantiated use -H:+TraceClassInitialization.
Detailed message:
Trace:
    at parsing org.wildfly.common.net.CidrAddress.<clinit>(CidrAddress.java:46)
Call path from entry point to org.wildfly.common.net.CidrAddress.<clinit>():
    no path found from entry point to target method

因此，我尝试的第一件事是指示类 org.wildfly.common.net.CidrAddress 不要在 Image BuildTime 初始化，而是在 Image RunTime 初始化，配置如下:

quarkus.native.additional-build-args=--initialize-at-run-time=org.wildfly.common.net.CidrAddress
quarkus.native.enable-jni=true 

但是，什么都没有改变。我还尝试激活(按照指示)参数 -H:+TraceClassInitialization，以找出可能导致问题的正在初始化的类。没有效果!它与此参数没有任何区别(无额外信息)。

其他人是否经历过这种情况？任何提示，想法？

谢谢!

Quarkus 尚不支持 GraalVM 19.3.0，它刚刚发布，需要进行一些更改。

特别是你遇到了这个问题: - https://github.com/quarkusio/quarkus/pull/5353

我希望 Quarkus 1.1 支持 GraalVM 19.3，但我不确定。
