OpenWebStart

brew install --cask openwebstart v1.13.0

Open-source replacement for Java Web Start that runs JNLP-based applications after Java 11 removed the feature.

Why you might care

Java Web Start was removed in Java 11, breaking legacy business applications that rely on JNLP. OpenWebStart is an open-source, enterprise-supported reimplementation that lets you continue running these applications without downgrading Java. Essential if you need to access older Java applets or corporate tools that haven't migrated to modern platforms.
