Substitution of environment / system properties for microprofile-opentracing-smallrye extension ----------------------------------------------------------------------------------------------- Key: WFLY-13341 URL: https://issues.redhat.com/browse/WFLY-13341 Project: WildFly Issue Type: Bug Components: MP OpenTracing Affects Versions: 19.0.0.Final Reporter: Yeray Borges Santana Assignee: Emmanuel Hugonnet Priority: Major I would like to able to configure the microprofile-opentracing-smallrye extension in wildfly 19 with substituted variables (environment or system). When I try this it seems the values are not resolved, for example {code:xml} <subsystem xmlns="urn:wildfly:microprofile-opentracing-smallrye:2.0" default-tracer="jaeger"> <jaeger-tracer name="jaeger"> <tags> <property name="env" value="${env.ENV}"/> <property name="user" value="joe"/> </tags> <sampler-configuration sampler-type="ratelimiting" sampler-param="1.0"/> <sender-configuration sender-endpoint="http://${JAEGER_AGENT_HOST}:14268/api/traces"/> </jaeger-tracer> </subsystem> {code} results in: {noformat} 2020-03-29 15:17:49,448 ERROR [jaeger.RemoteReporter-QueueProcessor] [] [] [] [] [] (io.jaegertracing.internal.reporters .RemoteReporter) QueueProcessor error:: java.lang.RuntimeException: java.net.URISyntaxException: Illegal character in au thority at index 7: http://${jaeger_agent_host}:14268/ at com.squareup.okhttp3//okhttp3.HttpUrl.uri(HttpUrl.java:385) at com.squareup.okhttp3//okhttp3.internal.connection.RouteSelector.resetNextProxy(RouteSelector.java:129) at com.squareup.okhttp3//okhttp3.internal.connection.RouteSelector.<init>(RouteSelector.java:63) at com.squareup.okhttp3//okhttp3.internal.connection.StreamAllocation.<init>(StreamAllocation.java:101) {noformat}
