我正在使用以下堆栈运行一个简单的 Java 应用程序(只是一个 REST 端点,一个“Hello”响应——正是由 Quarkus maven 原型生成的示例,无需修改):

  • Quarkus(微配置文件)
  • JDK 1.8 热点 1.8.0_231-b11
  • GraalVM 19.3.0(本机映像)
  • macOS 卡塔利娜

它是第一个错误(尽管它似乎不是主要问题):

[code-with-quarkus-1.0.0-SNAPSHOT-runner:1868]        setup:   8,524.65 ms
java.lang.NoSuchMethodException: com.oracle.svm.core.jdk.LocalizationSupport.addBundleToCache(java.lang.String)

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

所以,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!这个参数没有任何区别(没有额外的信息)。

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。

我的多阶段构建遇到了同样的问题:

首先我修改了我的 pom.xml:

          <build>
            <plugins>
                <plugin>
                    <groupId>io.quarkus</groupId>
                    <artifactId>quarkus-maven-plugin</artifactId>
                    <version>${quarkus.version}</version>
                    <executions>
                        <execution>
                            <goals>
                                <goal>native-image</goal>
                            </goals>
                            <configuration>
                                <enableHttpUrlHandler>true</enableHttpUrlHandler>
                                <enableHttpsUrlHandler>true</enableHttpsUrlHandler>
                                <enableJni>true</enableJni>
                                <additionalBuildArgs>--initialize-at-run-time=java.net.Inet6Address -H:+TraceClassInitialization</additionalBuildArgs>
                            </configuration>
                        </execution>
                    </executions>
                </plugin>

还是一样的错误...

然后我将 Dockerfile 的基本映像从 FROM quay.io/quarkus/centos-quarkus-maven:19.3.0-java8 AS build更改为FROM quay.io/quarkus/centos-quarkus-maven:19.2.1 AS build Here是我完整的 Dockerfile.multistage:

FROM quay.io/quarkus/centos-quarkus-maven:19.2.1 AS build
COPY src /usr/src/app/src
COPY pom.xml /usr/src/app/pom.xml
USER root
RUN chown -R quarkus /usr/src/app
USER quarkus
RUN mvn -f /usr/src/app/pom.xml -Pnative clean package

## Stage 2 : create the docker final image
FROM registry.access.redhat.com/ubi8/ubi-minimal
WORKDIR /work/
COPY --from=build /usr/src/app/target/*-runner /work/application
RUN chmod 775 /work
EXPOSE 8080
CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]
