java.lang.reflect.UndeclaredThrowableException with spring-ldap-core 2.3.2.RELEASE and above

[aplatt]

I am using the following version of Java:

openjdk version "1.8.0_312"
OpenJDK Runtime Environment (build 1.8.0_312-8u312-b07-0ubuntu1~18.04-b07)
OpenJDK 64-Bit Server VM (build 25.312-b07, mixed mode)

When I make the following lookup using StartTLS with spring-ldap-core 2.3.1.RELEASE for a non existent dn:

DefaultTlsDirContextAuthenticationStrategy tlsAuthStratagy = new DefaultTlsDirContextAuthenticationStrategy();
tlsAuthStratagy.setShutdownTlsGracefully(true);
contextSource.setAuthenticationStrategy(tlsAuthStratagy);
PoolingContextSource poolingContextSource = new PoolingContextSource();
poolingContextSource.setMaxActive(5);
poolingContextSource.setContextSource(contextSource);
proxy = new TransactionAwareContextSourceProxy(poolingContextSource);
LdapTemplate ldapTemplate = new LdapTemplate(proxy);
ldapTemplate.lookup(dn);

I receive the following exception as expected:

org.springframework.ldap.NameNotFoundException

However, from spring-ldap-core 2.3.2.RELEASE and above, I received the following exception:

java.lang.reflect.UndeclaredThrowableException

This only happens when I attempt to use StartTLS ie. call setAuthenticationStrategy().

Thanks for the report, @aplatt. The only commit I can see between those two releases that may be related is c0def85.

I have not been able to reproduce this yet, though I imagine it has something to do with the above arrangement is propagating exceptions. Does the UndeclaredThrowableException have a caused by or anything else that indicates what its cause is? Or, are you able to produce a GitHub sample that demonstrates the error?

[aplatt]

Yes, the cause is actually the exception that was thrown prior to spring-ldap-core 2.3.2.RELEASE. It appears that all the LDAP exceptions thrown prior to spring-ldap-core 2.3.2.RELEASE have been translated to java.lang.reflect.UndeclaredThrowableException exceptions with the cause being the original exception. Only when using StartTLS (see original code snippet above).
