cn1-app-kit: a cn1lib of the code the full-stack samples share by shai-almog · Pull Request #6152 · codenameone/CodenameOne

shai-almog · 2026-11-01T17:30:45Z

Adds maven/cn1-app-kit, a cn1lib with a client half and a server half (the backend-library format from #6139), built in the framework reactor and released with it at the framework's version.

Client (com.codename1.appkit): Net (generated-client call to ok/failed callbacks), Skeleton, Chart/Meter.
Server (com.codename1.appkit.server): Caller, Text, Grants, AccountSecurity, and the push senders (cloud, console, recording, misconfigured).
Nothing in the server half is a bean: a consuming server wires only what it declares.
release.yml confirms all three artifacts (-common, -backend, -lib) on R2; pr.yml runs SpotBugs over both halves.
Developer guide: "The app kit" under backend libraries.

The samples are deliberately not migrated here; they move onto the kit after a release carries it.

🤖 Generated with Claude Code

A cn1lib with a server half, built in the framework reactor and released with it at the framework's version: Net, Skeleton and Chart on the client; Caller, Text, Grants, AccountSecurity and the push senders on the server. The samples are not moved onto it here; that follows once a release carries it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

@bean

Grants was a component, so every server depending on the kit got it wired and needed an authorization server. It is now built from a @bean method like AccountSecurity's pieces. A null issuer no longer throws in tokenDecoder, the issuer requirement for production is documented, and the lib pom says what adding CSS or natives would need.

ParparVM vs HotSpot (JDK 25): macOS arm64

Runner CPU: Apple M1 (Virtual) (baseline macos-arm64)

Ratios are ParparVM / JDK 25: below 1.00x ParparVM is faster (time) or smaller (RAM). Median of 5 interleaved, paired rounds; every run's output was verified. A ratio more than 20% (time) / 25% (RAM) above its baseline in vm/selfhost/perf-baseline/ is a regression and fails; one that far below is an improvement, reported but not failed (a row whose calibration runs were noisier carries a wider tolerance), and for RAM the change must also exceed 0.05x in absolute terms. Both run unpinned on all of the runner's CPUs, with their own default thread counts.
