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

Going through the logs I found this:
{noformat}
07:11:11.250 [main] WARN org.jboss.weld.Bootstrap - WELD-ENV-000028: Weld initialization skipped - no bean archive found
{noformat}
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:
{noformat}
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]
{noformat}
Finally, in the code, I pinpointed the issue on ` * FileSystemBeanArchiveHandler ` * , but this holds true for all implementations of BeanArchiveHandler:
{code:java}
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
}
{code}
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.
