LDAP error with JDK 17, JDK 18

[kasemir]

Channelfinder compiles with JDK 18, but at startup it then fails with this type of error:

IllegalAccessError: class org.springframework.ldap.core.support.AbstractContextSource (in unnamed module ...

Workaround seems to be this:
java --add-exports java.naming/com.sun.jndi.ldap=ALL-UNNAMED -jar target/ChannelFinder-4.0.0.jar

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ldapContextSource' defined in class path resource [org/springframework/boot/autoconfigure/ldap/embedded/EmbeddedLdapAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.ldap.core.support.LdapContextSource]: Factory method 'ldapContextSource' threw exception; nested exception is java.lang.IllegalAccessError: class org.springframework.ldap.core.support.AbstractContextSource (in unnamed module @0x22f71333) cannot access class com.sun.jndi.ldap.LdapCtxFactory (in module java.naming) because module java.naming does not export com.sun.jndi.ldap to unnamed module

For those searching, here is a longer excerpt of this really long error message as seen with openjdk 17.0.2 (Debian 11).

--add-exports seems to do the trick.
