Error message

e.getMessage()

What it means

BusinessException carrying the raw IOException message from MainJFrame when resolving the window logo image URL fails. The code picks logo_local.png (offline) or logo_pro.png (online) from the classpath via DefaultResourceLoader and, on IOException, rethrows e.getMessage() directly as the business message.

Solutions

1. Confirm the matching logo asset exists on the classpath: logo_local.png when offline, logo_pro.png otherwise.
2. Rebuild the start module so frontend/static assets (including the logo pngs) are assembled into the jar/resources.
3. Align chat2db.network.status with the logo variant actually packaged.
4. Note the message is e.getMessage() verbatim — it is not localized, so treat it as a packaging/classpath defect, not a user-facing message.

Example fix

// before
imageUrl = resource.getURL();
// after: defensive fallback to whichever logo is present
Resource r = ConfigUtils.isOffline()
    ? resourceLoader.getResource("classpath:logo_local.png")
    : resourceLoader.getResource("classpath:logo_pro.png");
if (!r.exists()) r = resourceLoader.getResource("classpath:logo.png");
imageUrl = r.getURL();

Resource r = ConfigUtils.isOffline()
    ? resourceLoader.getResource("classpath:logo_local.png")
    : resourceLoader.getResource("classpath:logo_pro.png");
if (!r.exists()) throw new BusinessException("logo resource missing on classpath");

try { imageUrl = resource.getURL(); }
catch (java.io.IOException e) {
    log.error("logo resource unresolved", e);
    throw new BusinessException("logo resource unavailable", e);
}

When it happens

Trigger: resource.getURL() throws IOException because the packaged logo resource (logo_local.png / logo_pro.png) is absent from the classpath, the JAR/resource directory is unreadable, or the resource loader cannot resolve it.

Common situations: Desktop/JCEF build assembled without copying the logo asset into the jar; classpath resource renamed/removed; offline flag (chat2db.network.status=OFFLINE) selecting logo_local.png when only logo_pro.png is packaged; corrupted jar.
