Franz Forsthofer updated CAMEL-7055:
------------------------------------
Description:
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 writtin 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.
