[jdk11u-dev] RFR: 8309550: jdk.jfr.internal.Utils::formatDataAmount method should gracefully handle amounts equal to Long.MIN_VALUE

[Frederic Thevenet]

Hi,

This is a backport of JDK-8309550: jdk.jfr.internal.Utils::formatDataAmount method should gracefully handle amounts equal to Long.MIN_VALUE

Original patch does not apply cleanly to 11u as one of the modified file `src/jdk.jfr/share/classes/jdk/jfr/internal/util/ValueFormatter.java` does not exit prior to 21. Changes to other files apply cleanly.

GHA tests are enabled and amended to include `test/jdk/jdk/jfr` in, addition to what's in the default configuration.

Thanks.
