Virtual Threads for a scripting language in Java 8 without Loom

The article describes how Jactl enables secure, embeddable scripting on Java 8/11 systems to handle blocking operations without tying up event-loop threads, using continuations to pause and resume execution much like virtual threads in Java 21. For CIOs, the business value is higher throughput and simpler application design on legacy Java platforms, reducing the need for a full reactive rewrite while preserving compatibility and performance; strategically, it gives IT teams a bridge technology today and a clearer path to adopt virtual threads later.
