Summary: EOFException with FormattedMessage
Key: LOG4J2-1929
URL: https://issues.apache.org/jira/browse/LOG4J2-1929
Project: Log4j 2
Issue Type: Bug
Components: API
Affects Versions: 2.8.2
Reporter: Gary Gregory
Assignee: Gary Gregory
Fix For: 2.9
>From https://github.com/apache/logging-log4j2/pull/78:

To pass FormattedMessage completely we should pass string values from argArray
together with argArray.length.
For now there is such bug: on readObject it's InputStream brings length of
stringArgs but there is no values in InputStream to read. So if length > 0
there will be EOFException while reading null value from InputStream.

The unit test without the fix yields:
