调用 javafx.scene.effect.DropShadow 时 Javafx .exe 崩溃
Javafx .exe crashes while invoking javafx.scene.effect.DropShadow
我的原生 javafx 应用程序在调用 javafx.scene.effect.DropShadow 时在运行时崩溃。
该应用程序仅在我注释掉相关代码时才有效。如何使用 DropShadow 效果来实现？

TL;DR
反射列表中缺少 class com.sun.scenario.effect.impl.prism.PrMergePeer。添加它，重新构建原生镜像，就可以了。
说明
如果您的应用程序 运行 在 JVM/Hotspot 上正常（即通过 mvn javafx:run），并且在 运行 时间通过本机图像失败（即通过 mvn client:run)，通常是配置问题，可能很容易修复。
通常，它与反射列表中缺少 classes 有关，这会导致 class 未找到异常。
但是，有时，无法反射调用的缺失 class 不会引发异常，并且应用程序保持 运行ning，但会出现一些意外行为。 DropShadow 效果似乎就是这种情况。
这让事情更难追踪。 class not found 异常已经给出了 class 缺失的提示，但在当前情况下，运行time 异常本身并没有。
如这里所述，https://docs.gluonhq.com/#_jni_and_reflection，客户端插件在target/client/$arch-$os/gvm/reflectionconfig-$arch-$os.json下创建了一个反射配置文件，其中有一组JavaFX classes用于反射.
然而，这一套并不完整，有时会遗漏一些 classes。一旦确定了这些，就有两个选择：
- 将它们添加到 pom 中的
reflectionList，例如：
<plugin>
<groupId>com.gluonhq</groupId>
<artifactId>client-maven-plugin</artifactId>
<version>0.1.36</version>
<configuration>
<target>${client.target}</target>
<mainClass>${main.class}</mainClass>
<reflectionList>
<list>com.sun.scenario.effect.impl.prism.PrMergePeer</list>
</reflectionList>
</configuration>
</plugin>
- 在
src/main/resources/META-INF/substrate/config 下创建文件 reflectionconfig.json，并添加 class（以及所需的 fields/methods）：
{
"name":"com.sun.scenario.effect.impl.prism.PrMergePeer",
"methods":[{"name":"<init>", "parameterTypes":["com.sun.scenario.effect.FilterContext", "com.sun.scenario.effect.impl.Renderer", "java.lang.String"] }]
}
后者是首选选项，因为它仅包含给定 class 所需的方法和字段，而前者包含所有方法和字段。
无论如何，我们还是要找到失踪的class。我们可以从堆栈跟踪中检查涉及的 JavaFX classes，或者我们可以使用 GraalVM 图像代理，幸运的是，它会为我们做这件事。
GraalVM 图像代理
GraalVM 有一个 Java 代理创建反射配置文件（以及其他），但需要先 运行 在 Hotspot 上安装应用程序。
这可以组合如下：
创建文件夹 src/main/resources/META-INF/native-image。
将代理添加到 javafx-maven-plugin:
<plugin>
<groupId>org.openjfx</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>0.0.5</version>
<configuration>
<mainClass>${main.class}</mainClass>
<options>
<option>-agentlib:native-image-agent=config-merge-dir=src/main/resources/META-INF/native-image</option>
</options>
</configuration>
</plugin>
运行 mvn javafx:run，并探索所有可能的场景（因此代理可以在 运行 时间内发现 class 使用的资源和资源） .
浏览添加到 src/main/resources/META-INF/native-image 的文件。
在 DropShadow 效果失败的情况下，客户端插件生成的配置文件中唯一缺少的相关 class 是 com.sun.scenario.effect.impl.prism.PrMergePeer。
- 最后，运行 再次
mvn client:build client:run，以创建和 运行 本机图像。
如果您保留 src/main/resources/META-INF/native-image，其中的配置文件将与客户端插件已经创建的配置文件结合使用。或者，您可以删除它们，只需使用上面解释的两个选项之一：将 class 添加到 reflectionList 或创建一个 json 文件。
我的原生 javafx 应用程序在调用 javafx.scene.effect.DropShadow 时在运行时崩溃。
该应用程序仅在我注释掉相关代码时才有效。如何使用 DropShadow 效果来实现？

TL;DR
反射列表中缺少 class com.sun.scenario.effect.impl.prism.PrMergePeer。添加它，重新构建原生镜像，就可以了。
说明
如果您的应用程序 运行 在 JVM/Hotspot 上正常（即通过 mvn javafx:run），并且在 运行 时间通过本机图像失败（即通过 mvn client:run)，通常是配置问题，可能很容易修复。
通常，它与反射列表中缺少 classes 有关，这会导致 class 未找到异常。
但是，有时，无法反射调用的缺失 class 不会引发异常，并且应用程序保持 运行ning，但会出现一些意外行为。 DropShadow 效果似乎就是这种情况。
这让事情更难追踪。 class not found 异常已经给出了 class 缺失的提示，但在当前情况下，运行time 异常本身并没有。
如这里所述，https://docs.gluonhq.com/#_jni_and_reflection，客户端插件在target/client/$arch-$os/gvm/reflectionconfig-$arch-$os.json下创建了一个反射配置文件，其中有一组JavaFX classes用于反射.
然而，这一套并不完整，有时会遗漏一些 classes。一旦确定了这些，就有两个选择：
- 将它们添加到 pom 中的
reflectionList，例如：
<plugin>
<groupId>com.gluonhq</groupId>
<artifactId>client-maven-plugin</artifactId>
<version>0.1.36</version>
<configuration>
<target>${client.target}</target>
<mainClass>${main.class}</mainClass>
<reflectionList>
<list>com.sun.scenario.effect.impl.prism.PrMergePeer</list>
</reflectionList>
</configuration>
</plugin>
- 在
src/main/resources/META-INF/substrate/config下创建文件reflectionconfig.json，并添加 class（以及所需的 fields/methods）：
{
"name":"com.sun.scenario.effect.impl.prism.PrMergePeer",
"methods":[{"name":"<init>", "parameterTypes":["com.sun.scenario.effect.FilterContext", "com.sun.scenario.effect.impl.Renderer", "java.lang.String"] }]
}
后者是首选选项，因为它仅包含给定 class 所需的方法和字段，而前者包含所有方法和字段。
无论如何，我们还是要找到失踪的class。我们可以从堆栈跟踪中检查涉及的 JavaFX classes，或者我们可以使用 GraalVM 图像代理，幸运的是，它会为我们做这件事。
GraalVM 图像代理
GraalVM 有一个 Java 代理创建反射配置文件（以及其他），但需要先 运行 在 Hotspot 上安装应用程序。
这可以组合如下：
创建文件夹
src/main/resources/META-INF/native-image。将代理添加到
javafx-maven-plugin:
<plugin>
<groupId>org.openjfx</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>0.0.5</version>
<configuration>
<mainClass>${main.class}</mainClass>
<options>
<option>-agentlib:native-image-agent=config-merge-dir=src/main/resources/META-INF/native-image</option>
</options>
</configuration>
</plugin>
运行
mvn javafx:run，并探索所有可能的场景（因此代理可以在 运行 时间内发现 class 使用的资源和资源） .浏览添加到
src/main/resources/META-INF/native-image的文件。
在 DropShadow 效果失败的情况下，客户端插件生成的配置文件中唯一缺少的相关 class 是 com.sun.scenario.effect.impl.prism.PrMergePeer。
- 最后，运行 再次
mvn client:build client:run，以创建和 运行 本机图像。
如果您保留 src/main/resources/META-INF/native-image，其中的配置文件将与客户端插件已经创建的配置文件结合使用。或者，您可以删除它们，只需使用上面解释的两个选项之一：将 class 添加到 reflectionList 或创建一个 json 文件。
