I believe this error stems from the need for post-openjdj11 runtimes to 
be invoked with specific runtime switches "unsealing" JVM modules to 
allow ABCL to perform dynamic introspection.

In the case of "does not opens java.lang" the switch would be:

    java --add-opens java.base/java.lang=ALL-UNNAMED [...]

The necessary switches are viewable in the [CI scripting used to test 
ABCL][1].

https://github.com/armedbear/abcl/blob/master/ci/create-abcl-properties.bash#L16

The ABCL Ant build system has targets of the form 
"abcl.properties.autoconfigure.openjdk.N" where N denotes the integer of 
the JDK version which are perhaps the most user-accessible portions 
which can be used when building ABCL like

    ant abcl.properties.autoconfigure.openjdk.21 abcl

Since I gather that you are encountering these errors in using Docker 
images, you would unfortunately probably need to rebuild these Docker 
images with these switches present in the ABCL invocation script.
