[keycloak-dev] Why isn't the configuration/providers directory on my classpath when attempting to load a file?

[Marko Strukelj]

What about simply wrapping the call in your provider that triggers
third party loading the configuration with the TCCL wrapping code
like:

ClassLoader old = Thread.currentThread().getContextClassLoader();
try {
    Thread.currentThread().setContextClassLoader(getClass().getClassLoader());

    callThirdPartyLibrary();

} finally {
    if (old != null) {
        Thread.currentThread().getContextClassLoader(old);
    }
}

If third party library only loads its files at init time, then one
time call from within ProviderFactory init() should be enough, and
other invocations should not require the TCCL wrapping code.
