ServiceConfigurationError with "not a subtype" for external library in dev mode
**Describe the bug**
I get several ServiceConfigurationError exceptions with "not a subtype" message when initializing the GeoTools library suite, but only in dev mode. I've verified that the classes in the error messages are both included in the project, but also that they are in different jars (e.g. interface "CRSFactory" in gt-opengis, and "ReferencingObjectFactory" that implements CRSFactory in gt-referencing).
 

**Expected behavior**
No errors even in dev mode.

**Actual behavior**
Several error messages like this when GeoTools is first used: 
"java.util.ServiceConfigurationError: org.opengis.referencing.crs.CRSFactory: org.geotools.referencing.factory.ReferencingObjectFactory not a subtype"


**To Reproduce**
Steps to reproduce the behavior:
1. Start attached project 
2. Access http://localhost:8080/test
3. Check console for error messages

**Configuration**
No application.properties in use

**Screenshots**
(If applicable, add screenshots to help explain your problem.)

**Environment (please complete the following information):**
 - Output of `uname -a`: Linux 5.7.15-100.fc31.x86_64 #1 SMP Tue Aug 11 17:18:01 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux 
 - Output of `java -version`: openjdk 11.0.8 2020-07-14 / OpenJDK Runtime Environment 18.9 (build 11.0.8+10) / OpenJDK 64-Bit Server VM 18.9 (build 11.0.8+10, mixed mode, sharing) 
 - Quarkus version: 1.7.3.Final
 - Build tool: Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f) 

**Additional context**
I've created the smallest possible test case here, so there's no difference in behaviour between dev and prod mode, except from the error messages. In my application I get bugs in dev mode because some of the services from the libraries won't load.

I've looked at https://quarkus.io/guides/class-loading-reference without finding a solution.
I tried to use <parentFirstArtifact> with quarkus-bootstrap-maven-plugin (and include the complete dependency graph for "gt-referencing"), but that didn't have any effect.
