[ https://jira.jboss.org/jira/browse/JBSEAM-3984?page=com.atlassian.jira.pl... ] Marius Oancea commented on JBSEAM-3984: --------------------------------------- I think there is a problem with this fix. Because transactionMetadata is transient it can be null is come circumstances. You need to replace: private TransactionMetadata lookupTransactionMetadata(AnnotatedElement element) { TransactionMetadata metadata = transactionMetadata.get(element); if (metadata == null) { metadata = loadMetadata(element); } return metadata; } with something like: private TransactionMetadata lookupTransactionMetadata(AnnotatedElement element) { TransactionMetadata metadata = getTransactionMetadata().get(element); if (metadata == null) { metadata = loadMetadata(element); } return metadata; } private Map<AnnotatedElement, TransactionMetadata> getTransactionMetadata() { if (transactionMetadata == null) { transactionMetadata = new HashMap<AnnotatedElement, TransactionMetadata>(); } return transactionMetadata; } If you don't do this you will get NPE when an desereliased interceptor is used. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
