jdk.dynalink在Java9中的bootclasspath中不可见

我们的项目是使用Eclipse OSGi开发的,但也提供了通过jardesc文件导出的普通JAR .该项目使用ASM库和javaagent来invokevirtual与invokedynamic调用交换.

这在Java 7和8中运行良好.现在,我们升级到Java 9并移植我们的实现以供使用jdk.dynalink.

java --version`
java 9.0.4
Java(TM) SE Runtime Environment (build 9.0.4+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.4+11, mixed mode)

出口部分

OTRE_MIN:最小运行时和元对象协议部分.

OTRE_DYN:动态编织代码(ASM)和运行时的其余部分.

OTRE_AGEND:javaagent.

目前,OTRE_MIN还包括OTRE_DYN.所以一切都放入了bootclasspath.

我用以下代码启动程序

JVM_ARGS="-d64 -Xms1024m -Xmx4048m -ea"
MODULES="--add-reads jdk.dynalink=ALL-UNNAMED --add-reads java.base=ALL-UNNAMED"

${JAVA_HOME}bin/java $MODULES \
-Xbootclasspath/a:${OTRE_MIN} -javaagent:$OTREDYN_AGENT $JVM_ARGS \
-jar ...

但是,似乎 jdk.dynalink在bootclasspath上不再可见包.

我阅读了有关Java 9和模块系统的其他线程以及类加载器的更改,但它们没有提供任何解决方案.

如何使Java 9之前jdk.dynalink的类可见$OTRE_MIN？
