Using Spring Boot 2.0.6 with Spring Data LDAP and openjdk

I have a Spring Boot 2.0.6 application with spring-data-ldap 2.0.9.RELEASE, and I always get an java.lang.ClassCastException: java.naming/com.sun.jndi.ldap.LdapCtx cannot be cast to org.springframework.ldap.core.DirContextOperations exception when trying to retrieve all the distinguishedNames from an Active Directory tree. This problem occurs only while using openjdk (I tried using openjdk-9.0.4 and openjdk-10.0.2).

I get the following stack trace:

I went over the official Spring Boot 2.0.6 documentation and in the System Requirements section it states:

9. System Requirements

Spring Boot 2.0.6.RELEASE requires Java 8 or 9 and Spring Framework 5.0.10.RELEASE or above.

In addition the official Spring Data LDAP official documentation states:

2. Requirements
   Spring Data LDAP 2.x binaries requires JDK level 8.0 or later, Spring Framework 5.0.8.RELEASE or later, and Spring LDAP 2.3.2.RELEASE or later.

However this error doesn't occur if I use Java 1.8.0_181. Is there some compatibility issue with open-jdk that I am not aware of?
