https://bugs.openjdk.java.net/browse/JDK-8080511
This is an long overdue refresh of the jimage support in the JDK9-dev repo. This includes native support for reading jimage files, improved jrt-fs (java runtime file system) support for retrieving modules and packages from the runtime, and improved performance for langtools in the presence of jrt-fs. http://cr.openjdk.java.net/~jlaskey/hs-rt-jimage/webrev-top <http://cr.openjdk.java.net/~jlaskey/hs-rt-jimage/webrev-top> http://cr.openjdk.java.net/~jlaskey/hs-rt-jimage/webrev-jdk <http://cr.openjdk.java.net/~jlaskey/hs-rt-jimage/webrev-jdk> http://cr.openjdk.java.net/~jlaskey/hs-rt-jimage/webrev-hotspot <http://cr.openjdk.java.net/~jlaskey/hs-rt-jimage/webrev-hotspot> http://cr.openjdk.java.net/~jlaskey/hs-rt-jimage/webrev-langtools <http://cr.openjdk.java.net/~jlaskey/hs-rt-jimage/webrev-langtools> Details: - jrt-fs provides access, via the nio FileSystem API, to the classes in a .jimage file, organized by module or by package. - Shared code for jimage support converted to native. Currently residing in hotspot, but will migrate to it’s own jdk library https://bugs.openjdk.java.net/browse/JDK-8087181 <https://bugs.openjdk.java.net/browse/JDK-8087181> - A new archive abstraction for class/resource sources. - java based implementation layer for jimage reading to allow backport to JDK8 (jrt-fs.jar - IDE support.) - JNI support for jimage into hotspot. - White box tests written to exercise native jimage support.
