CompoundVM_8.17.3_linux_x64.tar.gz包含多余的jre/lib/ext/._nashorn.jar导致jtreg测试报错

[sendaoYan]

测试命令：

jtreg -va -nr -w tmp -jdk:/home/yansendao/JDK/binary/cvm/ ~/git/jdk8u-dev/jdk/test/jdk/jfr/jcmd/TestJcmdConfigure.java

结果：

STDERR:
error: error reading /home/yansendao/JDK/binary/cvm/jre/lib/ext/._nashorn.jar; error in opening zip file
Note: /home/yansendao/git/jdk8u-dev/test/lib/jdk/test/lib/Utils.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
1 error

TEST RESULT: Failed. Compilation failed: Compilation failed

这个用例失败与 jre/lib/ext/._nashorn.jar 的存在与否无关，是 hotspot8 和 hotspot17 jfr 实现差异导致，目前 cvm 没有验证过 jfr 相关功能。

这个用例失败与 jre/lib/ext/._nashorn.jar 的存在与否无关，是 hotspot8 和 hotspot17 jfr 实现差异导致，目前 cvm 没有验证过 jfr 相关功能。

这个报错，显示javac启动的时候尝试打开 jre/lib/ext/._nashorn.jar文件报错，应该跟jfr实现没有关系。如下命令可以演示该问题：

cat >> HelloWorld.java << EOF
public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello world!");
    }
}
EOF
./bin/java -version ; ./bin/javac HelloWorld.java

结果：

openjdk version "1.8.0_452"
OpenJDK Runtime Environment (build 1.8.0_452-cvm-b00)
OpenJDK 64-Bit Server VM (CompoundVM 8.17.3) (build 17.0.16+0, mixed mode)
error: error reading /home/yansendao/tmp/cvm/jre/lib/ext/._nashorn.jar; error in opening zip file
1 error

删除所有的._*.jar文件之后，javac即可正常工作：

find . -name "._*.jar" -delete ; ./bin/java -version ; ./bin/javac HelloWorld.java ; ./bin/java -cp . HelloWorld
openjdk version "1.8.0_452"
OpenJDK Runtime Environment (build 1.8.0_452-cvm-b00)

Hello world!
