Franz Forsthofer updated CAMEL-7055: ------------------------------------ Attachment: 0001-bug-CachedOutputStream-close.patch > NullPointerException at > FileInputStreamCache.<init>(FileInputStreamCache.java:52) in connection with > DataFormat.marshal > ----------------------------------------------------------------------------------------------------------------------- > > 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 > Priority: Critical > Fix For: 2.12.3 > > 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. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
