JNDI LDAP Threads & Loom

[Aleksei Efimov]

I've logged an RFE to investigate internal usage of virtual threads in the JNDI/LDAP provider:
https://bugs.openjdk.org/browse/JDK-8290559

We will investigate it once VTs are out of preview.

I am not familiar with the specifics of this particular mechanism (I can ask others who are), but I expect this kind of internal usage will be considered once virtual threads are out of preview.
