commit b92b275bb590c6e9c37ff5b89bbf4d1c15e46d5a Author: opencode <[email protected]> AuthorDate: Sun Nov 1 14:17:45 2026 +0100 Fail hard on unapplied properties in GenericNamingResourcesFactory A JNDI lookup that could not apply a configured property silently returned a half-built bean, which the container then cached for singleton resources. Now every address that is not reference metadata either reaches the object or fails the lookup with a NamingException naming what was not applied. - Booleans accept only true or false, ignoring case and surrounding whitespace - not the BeanFactory anything-but-true-is-false coercion - and an address carrying no content is applied to nothing. - Apply the BeanFactory-parity conversions: int, long, short, byte, float, double, char and boolean in primitive and boxed form, plus InetAddress, with the empty-value traps closed (no fabricated first character, no loopback for an empty host). - Consult a setProperty(name, value) bag only when the bean has no same-named single-argument setter; a boxed Boolean bag return is evaluated like a primitive one; the bag never absorbs a value the bean's own setter could not be given. - Failure logs and messages no longer echo configured values: a failing password setter would otherwise write the secret to the log. Fatal VirtualMachineErrors from constructors and setters propagate; the container's ExceptionUtils cannot be referenced from tomcat-jdbc.jar and the check is inlined until the helper is shared. - The class javadoc states the full lookup contract: any Reference is accepted, the loader order, one new public-no-arg-constructed instance per lookup, the reserved metadata addresses, the supported types and the strict boolean grammar. Direct regression tests cover every fix. --- .../jdbc/naming/GenericNamingResourcesFactory.java | 266 +++++++++--- .../tomcat/jdbc/pool/util/LocalStrings.properties | 9 +- .../tomcat/jdbc/naming/TestNamingFactory.java | 470 +++++++++++++++++++-- 3 files changed, 659 insertions(+), 86 deletions(-) diff --git a/modules/jdbc-pool/src/main/java/org/apache/tomcat/jdbc/naming/GenericNamingResourcesFactory.java b/modules/jdbc-pool/src/main/java/org/apache/tomcat/jdbc/naming/GenericNamingResourcesFactory.java index 294ec4c4e6..38c6f3258e 100644 --- a/modules/jdbc-pool/src/main/java/org/apache/tomcat/jdbc/naming/GenericNamingResourcesFactory.java +++ b/modules/jdbc-pool/src/main/java/org/apache/tomcat/jdbc/naming/GenericNamingResourcesFactory.java @@ -20,11 +20,13 @@ import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.net.InetAddress; import java.net.UnknownHostException; +import java.util.ArrayList; import java.util.Arrays; import java.util.Collections; import java.util.Enumeration; import java.util.HashSet; import java.util.Hashtable; +import java.util.List; import java.util.Set; import javax.naming.Context; @@ -53,14 +55,42 @@ import org.apache.tomcat.jdbc.pool.util.MessageFactory; * port="1527"/> * </code> * </pre> + * <p> + * The factory accepts any {@link Reference}, not only the container-managed + * {@code ResourceRef} that a {@code <Resource>} element produces.
