<core:init debug="true" jndi-pattern="@jndiPattern@"/>

[shane.bryzak]

Either debug is disabled (though it looks enabled from your config) or there is no hot deploy directory (dependent on which hot deploy strategy is used).  I recommend you set a breakpoint in Initialization.createHotDeployment() and check which of these conditions it is.

Sorry, thats a bug - https://jira.jboss.org/jira/browse/JBSEAM-3357. Once it's fixed, please test trunk.

Fixed in trunk, please test.
