| I'm running Weld in a jarinjar setup, and I've been getting
java.lang.IllegalStateException: Singleton not set for STATIC_INSTANCE => [] |

Going through the logs I found this:
07:11:11.250 [main] WARN org.jboss.weld.Bootstrap - WELD-ENV-000028: Weld initialization skipped - no bean archive found
|
After some analysis, I found that no bean archives were found because the BeanArchiveHandlers assume the archive 'ref' is either gonna be war:, file:*, or *jar:. In my case, since I'm running in a jarinjar runtime, it returns rsrc:; I can see the logs where Weld is having trouble with it:
07:11:11.245 [main] DEBUG org.jboss.weld.Bootstrap - WELD-ENV-000032: Processing bean archive reference: rsrc:META-INF/beans.xml |
07:11:11.246 [main] WARN org.jboss.weld.Bootstrap - WELD-ENV-000031: The bean archive reference rsrc:META-INF/beans.xml cannot be handled by any BeanArchiveHandler: [org.jboss.weld.environment.deployment.discovery.FileSystemBeanArchiveHandler@13c8ac77, org.jboss.weld.environment.servlet.deployment.ServletContextBeanArchiveHandler@4bdf]
|
Finally, in the code, I pinpointed the issue on `FileSystemBeanArchiveHandler`, but this holds true for all implementations of BeanArchiveHandler:
public BeanArchiveBuilder handle(String path) { |
boolean nested = false; |
File file; |
|
if (path.contains(JAR_URL_SEPARATOR)) { |
// Most probably a nested archive, e.g. "/home/duke/duke.jar!/lib/foo.jar" |
file = new File(path.substring(0, path.indexOf(JAR_URL_SEPARATOR))); |
nested = true; |
} else { |
file = new File(path); <--- steps in here |
} |
if(!file.canRead()) { |
return null; <--- returns here |
}
|
Instead of checking for a specific scheme, like `jar`, `war`, or `file`, it should be expanded to other URL schemes, as it is possible to do so, as long as there is an URLStreamHandler; which there is. |
