The java.security.acl API was terminally deprecated and has been removed in Java 14: see release notes:

blocks|key|561843|text|这个问题在2021年末就已经解决了(迟来总比不做好！)因此，您现在可以将JDK+17%2B与WildFly+26%2B一起使用。但是，请注意，您必须从以下几个方面进行非平凡的移动：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|561844|<subsystem+xmlns="urn:jboss:domain:security:1.2">

<login-module+code="org.jboss.security.auth.spi.DatabaseServerLoginModule"+flag="required">

This has been resolved as of late 2021 (better late than never!). So you can now use JDK 17+ with WildFly 26+. Note, however, you have to make the non-trivial move from:
<pre><code>&lt;subsystem xmlns=&quot;urn:jboss:domain:security:1.2&quot;&gt;
...
&lt;login-module code=&quot;org.jboss.security.auth.spi.DatabaseServerLoginModule&quot; flag=&quot;required&quot;&gt;
...
&lt;/login-module&gt;
&lt;/subsystem&gt;
</code></pre>
...to...
<pre><code>&lt;subsystem xmlns=&quot;urn:wildfly:elytron:15.0&quot;&gt;
...
&lt;security-realms&gt;
 &lt;jdbc-realm&gt;
 ...
 &lt;/jdbc-realm&gt;
&lt;/security-realms&gt;
&lt;/subsystem&gt;
</code></pre>
YMMV depending on your architecture, but basically you have to embrace Elytron.

I migrated a <a href="https://github.com/dwws-ufes/marvin" rel="nofollow noreferrer">Web application</a> that worked fine on WildFly 17 on Java 11 to the latest versions of both: WildFly 19 on Java 14. In the end I'm getting a <code>ClassNotFoundException: java.security.acl.Group</code>, probably because the Web application uses JAAS. 

Note that a similar Web application built following <a href="https://github.com/dwws-ufes/jbutler/wiki/Tutorial00" rel="nofollow noreferrer">a tutorial of my own</a> worked fine, but it doesn't use JAAS. That and the package <code>java.security.acl</code> made me think JAAS is related.

Searching the Web I found <a href="https://jira.jboss.org/projects/WFCORE/issues/WFCORE-4282" rel="nofollow noreferrer">issue WFCORE-4282 at WildFly's JIRA</a> which seems to imply that although they knew this <code>java.security.acl.Group</code> class was deprecated more than a year ago, WildFly 19 still requires it and Java 14 did actually remove it, thus causing the <code>ClassNotFoundException</code> for me.

Is my interpretation correct? Does WildFly 19 + Java 14 + JAAS = <code>ClassNotFoundException</code> necessarily or has anyone managed to make it work? Or maybe I'm doing something wrong? It just seems to me such a huge problem for JBoss to have overlooked on WildFly...

Update: I removed Java 14, installed Java 13, reinstalled Eclipse and WildFly and redeployed de application and it worked, so WildFly 19 + Java 13 + JAAS = OK!

我将一个在Java11上运行良好的迁移到了WildFly 17的最新版本:Java14上的WildFly 19。最后，我得到了一个ClassNotFoundException: java.security.acl.Group，这可能是因为这个Web应用程序使用JAAS。请注意，在之后构建的类似的Web应用程序运行良好，...
