Exception when the application does not have a dependency with Hilla

[javier-godoy]

Hilla is an optional dependency in version 5.1.0-SNAPSHOT of this addon.

AppLayoutAddon/pom.xml

Lines 89 to 93 in 46a3a0d

	<dependency>
	<groupId>dev.hilla</groupId>
	<artifactId>hilla</artifactId>
	<optional>true</optional>
	</dependency>

When I attempt to use the addon in an application that doesn't have a dependency with Hilla, the following exception is thrown (and the application doesn't start)

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'registerEndpointServiceInitListener' defined in URL [jar:file:/app.jar!/BOOT-INF/lib/app-layout-addon-5.1.0-SNAPSHOT.jar!/com/flowingcode/addons/applayout/listener/RegisterEndpointServiceInitListener.class]: Post-processing of merged bean definition failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [com.flowingcode.addons.applayout.listener.RegisterEndpointServiceInitListener] from ClassLoader [org.springframework.boot.loader.LaunchedURLClassLoader@1b604f19]

Expected behavior since Hilla is an optional dependency, I expect to be able to use the addon without a dependency with Hilla.
