java.lang.IllegalArgumentException: Failure in creating proxy URL. Proxy port is required!

[manusa]

Description

From https://github.com/quarkusio/quarkus/discussions/37137

It seems that environment variables such as:

ALL_PROXY=proxy-se-uan.ddc.teliasonera.net:8080
NO_PROXY=localhost

Are causing the following stack-trace:

 java.base/java.lang.Thread.run(Thread.java:1583) Caused by: java.lang.IllegalArgumentException: Failure in creating proxy URL. Proxy port is required! at
