actually it's not CDDL 1.1 + GPLv2 with classpath exception. Eclipse Public License 1/.02.0 is acceptable though. I think let's add a new section for "Eclipse Public License 2.0" under "Eclipse Public License 1.0"
For more details, check out Apache's thirdparty license policy: https://www.apache.org/legal/resolved.html

Done.You are right, I added EPL 2.0 section.

it also pulls transitive jars.
Honestly, it's a bit heavy to pull bunches of jars to just work around the access of sun.misc.Signal API. Could it be addressed by using reflection?

@pan3793 This change is likely based on related modifications in Ozone. If reflection is used, could you provide some specific implementation ideas?

@myandpr Is there any additional information?

Exactly, and the problem is that sun.misc package is no longer supported after JDK 9，even removed in a future release( related information: https://openjdk.org/jeps/260). @slfan1989 @pan3793
