JDK-8250784 - Shenandoah: A Low-Pause-Time Garbage Collector
Description
With the recent Shenandoah backport to jdk11u, we decided to optionally split metadata.xml so that Shenandoah can provide its own metadata-shenandoah.xml in a separate file. This avoids generating code for Shenandoah when Shenandoah is not present in the build.

However, the metadata.xml is also read at run-time, but metadata-shenandoah.xml is not present at run-time, nor would it be read with the current implementation of MetadataHandler.java. This makes the test jdk/jfr/tool/TestPrintJSON.java fail.

Fix-Request (11u): Review thread: https://mail.openjdk.java.net/pipermail/jdk-updates-dev/2020-August/003600.html The change reverts some parts of the big Shenandoah import to their original state (and also match better what is in jdk/jdk). It fixes a number of failing JFR tests.
