BootLoader.hasClassPath() NPE during native image execution with JDK 11

[gwenneg]

Describe the bug

The following error happens with most (if not all) Quarkus integration tests during the native image startup (after the generation ended successfully):

It seems ClassLoaders.bootLoader() returns null which shouldn't be possible from what I can see in the JDK code (but I may read it wrong). This looks like an upstream bug but I'd like some opinions about it here before creating a GraalVM issue.

To Reproduce
Steps to reproduce the behavior:

1. Build the Quarkus sources using JDK 11.
2. ./mvnw clean install -Dnative -Dquarkus.native.container-build=true -Dquarkus.native.builder-image=quay.io/quarkus/ubi-quarkus-native-image:19.3.0-java11 --projects :quarkus-integration-test-kogito

Environment:

• Output of uname -a: Linux pc-79.home 4.18.0-80.11.2.el8_0.x86_64 #1 SMP Tue Sep 24 11:32:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
• Output of java -version: openjdk version "11.0.5" 2019-10-15 LTS OpenJDK Runtime Environment 18.9 (build 11.0.5+10-LTS) OpenJDK 64-Bit Server VM 18.9 (build 11.0.5+10-LTS, mixed mode, sharing)
• GraalVM version (if different from Java): 19.3.0
• Quarkus version or git rev: master

Additional context
The native image build is done using a Docker image.

I'm self-assigning this because I'm currently trying to work around this NPE using substitutions (which might not be the good way to fix it).
