JDK 17, 18 support

When I run maven-javadoc-plugin:jar built on top of this library I get the following exception:

Please add JDK 17 and 18 support as soon as possible. This is a blocker for developers using these versions.

This issue should already be fixed by 603c159. All you need to do now is cut a release.

[cowwoc]

If you upgrade to ASM 9.3 you can pick up JDK 19 support at the same time: https://asm.ow2.io/versions.html

[slawekjaranowski]

Commit 603c159 is in release 1.1.1

ASM 9.3 add support for Java 19, so Java 17 and 18 are supported in the latest release

Sorry for the false-alarm, you are right. I was mistakenly running JDK17-specific configuration using a JDK11 runtime.
