## 🏗️ Architecture & Design Patterns

### Core Design Principles
CoreLib follows a **utility-class pattern** where most functionality is exposed through static methods:

            themeHelper.getJarFile(artifact);
            fail("Should throw ThemeException");
        } catch (Exception e) {
            // Should throw ThemeException or other exception related to file not found
            assertTrue(e.getMessage().contains("does not exist") || e instanceof ThemeException);
        }
    }

    @Test
    public void test_closeQuietly_nonExistentDirectory() {

    }

    /**
     * Set the user name which is used to setup <code>GSSContext</code>. If null
     * is set, the default user will be used which is retrieved from the first
     * TGT found in <code>Subject</code> .
     *
     * @param name
     *            the user name used to setup <code>GSSContext</code>
     */
    public void setUser(String name) {
        this.user = name;
    }

			idx = i
		}
	} else {
		idx = globalEndpoints.GetPoolIdx(v)
	}

	if idx == -1 {
		apiErr := toAdminAPIErr(ctx, errInvalidArgument)
		apiErr.Description = fmt.Sprintf("specified pool '%s' not found, please specify a valid pool", v)
		// We didn't find any matching pools, invalid input
		writeErrorResponseJSON(ctx, w, apiErr, r.URL)
		return
	}

	status, err := pools.Status(r.Context(), idx)

    }

    @Test
    public void test_crawlerHotthreadType() {
        assertEquals("cpu", fessConfig.getCrawlerHotthreadType());
    }

    // Test property not found exception
    @Test
    public void test_propertyNotFound() {
        try {
            fessConfig.get("non.existent.property");
            fail("Should throw ConfigPropertyNotFoundException");
