[jira] [Commented] (FREEMARKER-119) TemplateException throws NPE
after deserialization
[ https://issues.apache.org/jira/browse/FREEMARKER-119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16916194#comment-16916194 ]
Daniel Dekany commented on FREEMARKER-119:
------------------------------------------
{{TemplateException.readObject(ObjectInputStream)}} initializes the {{lock}} field during standard deserialization. There's even a test case for that. I'm not yet sure what Hessian and Burlap does, but will check that.

> Key: FREEMARKER-119
> URL: https://issues.apache.org/jira/browse/FREEMARKER-119
> Project: Apache Freemarker
> Issue Type: Bug
> Components: engine
> Affects Versions: 2.3.27-incubating, 2.3.29
> Reporter: Alex Poruchikov
> Priority: Major
>
> freemarker.template.TemplateException cannot be deserealized properly, because of transient field "lock", used in getMessage() method. See line 441 in TemplateException.java.
> It throws NPE when getMessage() method is called on deserialized object.
> Problem appears, at least, with Hessian and Burlap serialization protocols from Caucho.com.
