[jboss-jira] [JBoss JIRA] (WFCORE-763) Persisting an empty list [] gets read as a list with empty string [""] resulting in IllegalArgumentException

[ https://issues.jboss.org/browse/WFCORE-763?page=com.atlassian.jira.plugin... ] Paul Ferraro updated WFCORE-763: -------------------------------- Description: In short, the default AttributeParser/AttributeMarshaller for list attributes do not handle empty lists in a symmetric fashion. e.g. if I persist an empty list to xml, and read it back again, using the default parser/marshaller, I should get back an empty list. Instead I get back a list of size 1 containing an empty string. Affects at least infinispan aliases and modcluster proxies...
