Ldap style oracle jdbc urls not supported for native

[vsevel]

Describe the bug

If I use a url jdbc:oracle:thin:@ldap://..., I get the following error at startup: java.lang.ClassNotFoundException: com.sun.jndi.ldap.LdapCtxFactory]

Expected behavior

Should work same as non ldap oracle jdbc url.

Actual behavior

Here is the full exception:

How to Reproduce?

Create an application using the quarkus-jdbc-oracle driver.
Compile the application in native.
Run the application with a url of type: quarkus.datasource.jdbc.url=jdbc:oracle:thin:@ldap://....
The application fails at startup.

Output of uname -a or ver

No response

Output of java -version

No response

GraalVM version (if different from Java)

GraalVM 21.1.0 Java 11 CE (Java Version 11.0.11+8-jvmci-21.1-b05)

Quarkus version or git rev

2.1.0

Build tool (ie. output of mvnw --version or gradlew --version)

No response

Additional information

Note that the application works with tns style url: quarkus.datasource.jdbc.url=jdbc:oracle:thin:@(DESCRIPTION=(ENABLE=BROKEN)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)... (the address resolved by ldap).
So the issue is really about ldap access, not oracle.

could this be linked to #18385?

@gsmet I have a similar issue with the following trace:

Caused by: java.lang.ClassNotFoundException: com.sun.jndi.ldap.LdapCtxFactory

Can someone knowledgeable have a look, please?

[vsevel]

this can be solved using @RegisterForReflection(classNames = { "com.sun.jndi.ldap.LdapCtxFactory" })

It's going to be fixed in 2.6.1.Final thanks to #22452 .
