["Michał Warecki (Commented JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-4230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13224237#comment-13224237 ] 

Michał Warecki commented on CAMEL-4230:
---------------------------------------

I think it can be done as in the case IllegalArgumentException:

protected Object invoke(Method mth, Object pojo, Object[] arguments, Exchange exchange) throws InvocationTargetException {
        try {
            return mth.invoke(pojo, arguments);
        } catch(IllegalAccessException e) {
            throw new RuntimeExchangeException("IllegalAccessException occurred invoking method: " + mth + " using arguments: " + Arrays.asList(arguments), exchange, e);
        } catch (IllegalArgumentException e) {
            throw new RuntimeExchangeException("IllegalArgumentException occurred invoking method: " + mth + " using arguments: " + Arrays.asList(arguments), exchange, e);
        }
    }
