Configuring the SpiffeProvider in java.security is not adding the Provider

まず、示されている java.security ファイルを使って Spring Boot の実行可能 JAR の起動を再現し、IntelliJ からの実行と比較します。SpiffeProvider.install() 周辺のプロバイダー読み込みと、KeyStore.getInstance の失敗を追跡し、java.policy は制御されたバリエーションとしてのみ使用します。完了条件は、install() に依存せずに、実行可能 JAR から Spiffe が利用できない理由を説明するか修正することです。

I am trying to plugin the SpiffeProvider using just the java.security properties file, but this is not working for some reason. Can you please help me figure this out? I have to also mention that I don't rely on the SpiffeProvider.install()

The java.security content

# The provider sequence, 11 is accurate 
security.provider.11=io.spiffe.provider.SpiffeProvider
# Determines the default key and trust manager factory algorithms for
# the javax.net.ssl package.
#
ssl.KeyManagerFactory.algorithm=Spiffe
ssl.TrustManagerFactory.algorithm=Spiffe

# list of accepted SPIFFE IDs
ssl.spiffe.accept=spiffe://example.org/myservice

Please see this commit on my fork https://github.com/alwaysastudent/java-spiffe-examples/commit/805a56d768489733d643bbcc01ac01fd6f9b4ebf where I am trying to test a spring boot application jar.

The way I am running this example is by

java-spiffe-examples/spring-boot-x509-demo]$ java -Djava.security.debug=properties -Djava.security.policy=java.policy -Djava.security.properties=java.security -jar ./backend/build/libs/backend-0.1.jar


properties: reading security properties file: /Users/alwaysastudent/.sdkman/candidates/java/8.0.272.hs-adpt/jre/lib/security/java.security
properties: reading security properties file: file:/Users/alwaysastudent/dev/temp-projects/fork/java-spiffe-examples/spring-boot-x509-demo/java.security

But I am getting the following error

java.security.KeyStoreException: Spiffe not found

I tried with and without the java.policy file and it does not work in both cases. If I run the program from intellij it works, but when I run this as an executable jar it does not. Kindly help understand the problem.
