Problem using Cipher*Stream and Properties

Question

I ran into a tricky problem using CipherInputStream, CipherOutputStream and Properties. I don't seem to find where I'm doing something wrong here.
I have something like this:
encCipher; // and already initiated ENCRYPTION Cipher
FileInputStream fis = new FileInputStream( "textfile.properties" );
// textfile is an unencrypted text-file containing:
// prop1=valueprop1
// prop2=valueprop2
// prop3=valueprop3
Properties props = new Properties();
props.load( fis );
FileOutputStream fos = new FileOutputStream( "enctextfile.properties" );
CipherOutputStream cos = new CipherOutputStream( fos, encCipher );
props.store( cos );Up until here, no problems right? I get the contents from the source text-file, and then write with to the CipherOutputStream, which gives me an encrypted version of the original file.
Then: (assume decCipher is an already initiated DECRYPTION Cipher)
FileInputStream fis = new FileInputStream( "enctextfile.properties" );
CipherInputStream cis = new CipherInputStream( fis, decCipher);
Properties props = new Properties();
props.load( cis );
props.list( System.out ); // this line should produce the exact same contents as the original source file right?But the output has one property less, as if in some part of this process, data has been lost. But where? Am I missing something?
Thanks in advance for any hints,
Chris

Yes. Just now I realize I must close it for all the
buffer to be written out to the file.:-) My crystal ball is working well today!
