> Key: CAMEL-7055
> URL: https://issues.apache.org/jira/browse/CAMEL-7055
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.11.2, 2.12.2
> Reporter: Franz Forsthofer
> Assignee: Claus Ibsen
> Fix For: 2.12.3, 2.13.0
>
> Attachments: 0001-bug-CachedOutputStream-close.patch
>
>
> Stack Trace:
> {code}
> Caused by: java.lang.NullPointerException
> at
> org.apache.camel.converter.stream.FileInputStreamCache.<init>(FileInputStreamCache.java:52)
> at
> org.apache.camel.converter.stream.CachedOutputStream.newStreamCache(CachedOutputStream.java:199)
> at
> org.apache.camel.processor.MarshalProcessor.process(MarshalProcessor.java:79)
> {code}
> Error occurs, if streamCache is true and the stream is put into the file
> system because the spool threashold is reached.
> The following is happening:
> The Marshall Processor handels over to the DataFromat.marshal method a
> CachedOutputStream instance. In the marschal method data are written into the
> output stream, when the spool threshold is reached the data are streamed into
> the file system. Finally the output stream is closed and the
> CachedOutputStream instance deletes the cached file during closing. The next
> processor tries to read the FileInputStreamCache and gets the
> NullPointerException.
> Currently this problem can occur in the following DataFormat classes (because
> they close the stream, which is actually correct):
> GzipDataFormat
> CryptoDataFormat
> PGPDataFormat
> SerializationDataFormat
> XMLSecurityDataFormat
> ZipDataFormat
> My proposal is not to delete the cached file during closing the output
> stream. The cached file shall only be closed on the onCompletion event of the
> route. See attached patch.
