Setting javax.net.ssl.trustStore to a file with only the corporate CA replaces the default roots. Validation failure is wrapped as 'PKIX path building failed: ' + SunCertPathBuilderException('unable to find valid certification path to requested target'). Fix status: documented_behavior Limitations: - OS-backed truststore type names are from general JDK knowledge, not verified in fetched sources here. Other error fragments: - unable to find valid certification path to requested target Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/openjdk/jdk/1587398892ce98284c9c994b14696a96cd43e1ed/src/java.base/share/classes/sun/security/ssl/TrustStoreManager.java (official_docs, unknown, documented_behavior): Trust store resolution order: javax.net.ssl.trustStore property, jssecacerts, cacerts. - https://raw.githubusercontent.com/openjdk/jdk/1587398892ce98284c9c994b14696a96cd43e1ed/src/java.base/share/classes/sun/security/validator/PKIXValidator.java (official_docs, unknown, documented_behavior): Wraps failures as ValidatorException('PKIX path building failed: ' + e). - https://raw.githubusercontent.com/openjdk/jdk/1587398892ce98284c9c994b14696a96cd43e1ed/src/java.base/share/classes/sun/security/provider/certpath/SunCertPathBuilder.java (official_docs, unknown, documented_behavior): Throws SunCertPathBuilderException 'unable to find valid certification path to requested target'.
