Tobias Gierke updated WICKET-7168:
----------------------------------
Summary: ByteBuddy proxy crashes in constructor when proxied class
constructor invokes a non-private member method (was: ByteBuddy proxy crashes
in constructor when proxied class invokes a non-private member method)

> Key: WICKET-7168
> URL: https://issues.apache.org/jira/browse/WICKET-7168
> Project: Wicket
> Issue Type: Bug
> Components: wicket-ioc
> Affects Versions: 10.7.0
> Reporter: Tobias Gierke
> Priority: Major
>
> Hi,
> In our Spring context / application we have a Spring bean that looks like
> this:
> {code:java}
> public class ConditionFactory {
> public ConditionFactory() {
> registerDefaultHandlers();
> }
> // package-level visibility for unit testing
> void registerDefaultHandlers() {
> ....
> }{code}
> that code used to work flawlessly until we upgraded from Wicket 9 on JDK 21
> to Wicket 10.0.7 on JDK 25 (so either one of those changes may be the
> culprit).
> The exception we're now getting when Wicket is trying to instantiate a proxy
> for this class is this:
> {code:java}
> Caused by: org.apache.wicket.WicketRuntimeException:
> java.lang.reflect.InvocationTargetException
