From d6e74592607cf1e304fa7bf9de77fe50a4a38068 Mon Sep 17 00:00:00 2001 From: Shai Almog <67850168+shai-almog@users.noreply.github.com> Date: Wed, 27 May 2026 18:04:10 +0300 Subject: [PATCH 1/4] Add local ParparVM-backed JavaScript builder gated to Enterprise tier JavaScriptBuilder mirrors the IPhoneBuilder/AndroidGradleBuilder pattern for the new ParparVM-based JS port, replacing the ad-hoc build script. Gated at the Enterprise user-level threshold (rank >= 12000) via the javascript.userLevel build hint or the CN1_USER_LEVEL env var; lower or unknown tiers see a clear licensing error before any work runs. CN1BuildMojo dispatches local-javascript builds to the new builder and explicitly bundles codenameone-core/java-runtime into the staged jar since their provided scope is non-transitive on child modules.

The suite-level skip in Cn1ssDeviceRunner.shouldForceTimeoutInHtml5 doesn't catch this because it sees an unexpected platform name on the JS port. CN.getPlatformName() reliably reports "HTML5" here, so self-skip from runTest() and call done() to advance the suite. Re-applies the fix from e0cd604d2 that was reverted in e3dd0c9f6 alongside unrelated diag cleanup.
