Custom ClassLoader behaves differently under JVM and Native Image

Describe the issue A clear and concise description of the issue. We recommend using the latest snapshot builds to replicate the issue as bugs are constantly being fixed in the master branch

Custom ClassLoader behaves differently under JVM and Native Image.
The custom ClassLoader passed the Apache DBCP2 unit test normally under the JVM, but after collecting the GraalVM reachability metadata, the unit test failed in the nativeTest link. I have a Git to reproduce this problem, refer to https://github.com/linghengqian/driver-classloader-graalvm-test.
This issue was found at https://github.com/oracle/graalvm-reachability-metadata/issues/202 . Just a link to https://github.com/apache/shardingsphere/issues/21347 from an earlier investigation.

Steps to reproduce the issue Please include both build steps as well as run steps

[e.g.: git clone --depth 1 https://git.myrepo.com/projectone ]
[e.g.: mvn clean package]

sudo apt install unzip zip curl sed -y
curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install java 22.3.1.r17-grl
sdk use java 22.3.1.r17-grl

gu install native-image
sudo apt-get install build-essential libz-dev zlib1g-dev -y

git clone git@github.com:linghengqian/driver-classloader-graalvm-test.git
cd ./driver-classloader-graalvm-test/
./gradlew -Pagent clean test
./gradlew metadataCopy --task test
./gradlew clean nativeTest

Describe GraalVM and your environment:

GraalVM version (latest snapshot builds can be found here), or commit id if built from source: [e.g. EE 19.3, CE 20.0, CE 20.1.0-dev-20200304_0848] CE 22.3.1
JDK major version: [e.g.:8] 17
OS: [e.g. macOS Catalina] Ubuntu 22.04
Architecture: [e.g.: AMD64] AMD64

More details Consider adding the --native-image-info and --verbose flags when building your native image and paste output below.

Add any other information about the problem here. Especially important are stack traces or log output. Feel free to link to gists or to screenshots if necessary.
