Java, Life is Short!
summary
Shows concrete shortcuts: use jbang with GPT preview to generate runnable Java scripts and CLI templates, use SDKMAN to install and switch Java 8/11/17/21 (audience notes Java 21 adoption in production is essentially zero), use Quarkus Dev + Dev Services spins up Postgres via Testcontainers for instant live reload and scoped test containers, run quarkus image build or image build --jib for container images, add OpenTelemetry and Micrometer for tracing/metrics, and use JReleaser to automate releases. Demo partially fails when internet is absent.
