This is an umbrella issue tracking the progress of converting JUnit 3, JUnit 4, and TestNG-based test to using JUnit Jupiter API (aka JUnit).

The following command prints an overview of how many tests are using the "testng" runner via the jtreg syntax:

    find test/* -name \*.java | xargs grep '@run' | grep testng | grep "java:" | cut -d : -f 1 | cut -d / -f 1-3 | sort | uniq -c | sort -nr

It will show something similar to

```
1299 test/jdk/java
 891 test/jaxp/javax
 151 test/jdk/jdk
 138 test/hotspot/jtreg
 101 test/langtools/jdk
  65 test/langtools/tools
  62 test/jdk/sun
  54 test/jdk/tools
  39 test/jdk/com
  25 test/jdk/sanity
  14 test/jdk/javax
   5 test/lib-test/jdk
```

Dedicated sub-tasks will be created for components/groups.
