[Denis Maliarevich (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBIDE-4104?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12460739#action_12460739 ] 

Denis Maliarevich commented on JBIDE-4104:
------------------------------------------

The cause of the exception is missing "value" attribute. String reader based on the value attribute string is created to parse this text. When there is no value, string reader are created with "null" argument and the exception is thrown.

The soulution is to create a default empty string value to pass to the string reader. And now when there is no value attribute string reader will be created with empty string argument.
