Java: how to make sense out of cryptic stack traces?

While trying to run a unit test, I get the following stack trace. I don't even know where to start looking (read my comment below).

Where should I start and what would you do to solve this?

(note that the following stack trace is basically how I get it from Eclipse, without any formatting or anything: just countless lines of about 120 chars each) [I only pasted the five lines where apparently the problem happens]

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'acceptanceChain' defined in class path resource 

[.../chain/connector/...xml]: Cannot resolve reference to bean 'xxxCommand' while setting constructor argument with key [0]; nested exception is

Any help is very welcome.

Take the signifiant part of the message :

Error creating bean with name 'acceptanceChain' defined in class path resource 

I guess the bean acceptanceChain can't be instanciated. Maybe because it has a boolean parameter in which one tries to inject a LinkedHashMap, as the following message states :

Failed to convert value of type [java.util.LinkedHashMap] to required type [boolean]
