Claus Ibsen created CAMEL-25971:
-----------------------------------
Summary: camel-exec - an ExecResult without output does not
convert to a byte array
Key: CAMEL-25971
URL: https://issues.apache.org/jira/browse/CAMEL-25971
Project: Camel
Issue Type: Bug
Components: camel-exec
Affects Versions: 4.18.0, 4.22.0, 4.23.0
Reporter: Claus Ibsen
Fix For: 4.24.0
When the command writes nothing to its standard output, the ExecResult does not
convert to a byte array: {{ExecResultConverter.convertToByteArray}} passes the
null stream to {{IOUtils.toByteArray}} (main e6885df7894d, line 55), which
throws a NullPointerException. The conversion to a String gives "" in the same
case.
Checked on 4.24.0-SNAPSHOT with {{camel run}}: after {{to: exec:true}},
{{convertBodyTo: byte[]}} fails with {{InvalidPayloadException: No body
available of type: byte[] but has type:
org.apache.camel.component.exec.ExecResult}}, caused by the error of the type
conversion.
*Proposed change*: return an empty byte array when there is no output, as the
String converter does.
