No CDI container is available

Error message

No CDI container is available

What it means

ArcCDIProvider.getCDI() throws IllegalStateException when Arc.container() returns null, meaning no CDI container has been initialized (or it was already shut down). CDI.current()/CDIUtils require a running Arc container to return a CDI handle.

Solutions

1. Ensure the application/container is started before calling CDI.current() (in Quarkus, run within a @QuarkusTest or the running app)
2. In plain tests, call Arc.initialize() first and Arc.shutdown() in @AfterAll
3. Avoid static-initializer use of CDI.current(); obtain beans lazily at runtime
4. Check for accidental Arc.shutdown() calls or container restarts preceding the access

Example fix

// before
MyBean b = CDI.current().select(MyBean.class).get(); // IllegalStateException in plain test
// after
Arc.initialize();
try {
    MyBean b = CDI.current().select(MyBean.class).get();
} finally {
    Arc.shutdown();
}

ArcContainer c = Arc.container(); if (c == null) { Arc.initialize(); }

boolean ready = Arc.container() != null;

try { CDI<Object> cdi = CDI.current(); } catch (IllegalStateException e) { Arc.initialize(); CDI<Object> cdi = CDI.current(); }

When it happens

Trigger: Calling CDI.current() or the CDIProvider.getCDI() before Arc.initialize(), after Arc.shutdown(), or in a process/ClassLoader where the Arc container was never started (plain unit tests, static initializers, early startup code).

Common situations: Unit tests exercising CDI code without QuarkusTest; code running in a static field initializer before the container boots; use of CDI.current() in a separate thread before/after application lifecycle; calling CDI.current() during container shutdown.
