Opentracing extension: java.lang.reflect.InvocationTargetException: Illegal character in authority

[jamesfalkner]

Describe the bug
When building an app with the OpenTracing extension, and specifying an environment variable in the definition of an application property in application.properties:

quarkus.jaeger.endpoint=http://${JAEGER_ENDPOINT:jaeger-tracing}:14268/api/traces

The application fails to build (jvm or native) with

[ERROR] Failed to execute goal io.quarkus:quarkus-maven-plugin:0.22.0:build (default) on project getting-started: Failed to build a runnable JAR: Failed to build a runner jar: Failed to augment application classes: java.lang.reflect.InvocationTargetException: Illegal character in authority at index 7: http://${JAEGER_ENDPOINT:jaeger-tracing}:14268/api/traces -> [Help 1]

Expected behavior
App builds and runs with no errors and the property is settable via environment variable at runtime.

Actual behavior
Unable to build (See above). If I rename the property to anything else, e.g.

quarkus.foobar.endpoint=http://${JAEGER_ENDPOINT:jaeger-tracing}:14268/api/traces

it works. If I set it to a value not using an environment variable, it also works:

quarkus.jaeger.endpoint=foo

To Reproduce
Steps to reproduce the behavior:
1.

mvn io.quarkus:quarkus-maven-plugin:0.21.1:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=getting-started \
    -DclassName="org.acme.quickstart.GreetingResource" \
    -Dpath="/hello" -Dextensions="opentracing"

Add variable definition to src/main/resources/application.properties

3. mvn clean package -DskipTests

Configuration

# Add your application.properties here, if applicable.

There's a good change you're hitting this issue: #3516 and that the env variable is not expanded and Jaeger refuses either $ or { in the URL.

@dmlloyd what's the status of this one? It's an issue that often gets reported.

It's in progress, but keeps getting bumped down due to one-off issues... sorry. I'll try to get it done ASAP.
