> This is the implementation of the draft [JEP: Ahead-of-time Command Line > Ergonomics](https://bugs.openjdk.org/browse/JDK-8350022) > > - Implemented new flag `AOTCacheOutput`, which can be used to create an AOT > cache using the "one-command workflow" > - Added processing of the `JAVA_AOT_OPTIONS` environment variable that can > supply extra VM options when creating an AOT cache > - Added `%p` substitution for `AOTCache`, `AOTCacheOutput`, and > `AOTConfiguration` options > > Please see the [JEP](https://bugs.openjdk.org/browse/JDK-8350022) and > [CSR](https://bugs.openjdk.org/browse/JDK-8356010) for detailed specification. > > Examples: > > > # Create an AOT cache with a single command: > $ java -cp HelloWorld.jar -XX:AOTMode=record -XX:AOTCacheOutput=foo.aot > HelloWorld > Hello World > Temporary AOTConfiguration recorded: foo.aot.config > Launching child process /usr/bin/java to assemble AOT cache foo.aot using > configuration foo.aot.config > Picked up JAVA_TOOL_OPTIONS: -Djava.class.path=HelloWorld.jar > -XX:AOTCacheOutput=foo.aot -XX:AOTConfiguration=foo.aot.config > -XX:AOTMode=create > Reading AOTConfiguration foo.aot.config and writing AOTCache foo.aot > AOTCache creation is complete: foo.aot 10240000 bytes > > # Create logging file for the AOT cache assembly phase > $ export AOT_TOOL_COMMAND=-Xlog:cds:file=log.txt > $ java -cp HelloWorld.jar -XX:AOTMode=record -XX:AOTCacheOutput=foo.aot > HelloWorld > > > Note: the child process is launched with Java API because the HotSpot native > APIs are not sufficient (no way to set env vars for child process).
