Never returns from zipAndEncrypt call executing in Linux environment

[GoogleCodeExporter]

Inside a WebApp running in a Tomcat Server in a Red Hat Enterprise Linux
Server release 5.4, the thread remains "suspended" permanently after
calling AesZipFileEncrypter.zipAndEncrypt

My code snippet looks like this:

Logger log = Logger.getLogger("TEST");

File tmpDir = new File(System.getProperty("java.io.tmpdir")) ;
File fLocal = new File( tmpDir, "filetocompress.txt" ) ;
final File rutaZip = new File(tmpDir, "encrypted.zip");
log.info("Creating "+rutaZip.getCanonicalPath()) ;

AesZipFileEncrypter azfe = new AesZipFileEncrypter(rutaZip);
azfe.zipAndEncrypt( fLocal, "passw" );
log.info("    added "+fLocal.getCanonicalPath()) ;

So far, the program never reaches the "added.." log trace print.
In disk, I can see the contents of java.io.tmpdir folder as follows:

-rw-r--r-- 1 tomcat tomcat       0 may 27 10:36 encrypted.zip
-rw-r--r-- 1 tomcat tomcat   68608 may 27 10:36 filetocompress.txt
-rw-r--r-- 1 tomcat tomcat   17709 may 27 10:36 filetocompress.txt.zip

So, it seems as if the zipping did worked, but not the following step of
encrypting it and putting it into the encrypted.zip file.

I cannot give more information because it's a remote server and so I can't
make a more accurate debug. I only know that the thread never retuns, but
stays running at some loop along the addEncrypted method.

Does the problem also occur in a "stand-alone" setup on your local machine (unix
environment)? If so, can you provide "filetocompress.txt" for debugging 
purposes?

Curiously, in my local machine it executes with no problem. True to say that 
it's a
Windows machine instead :-)

But in the server (Linux) the executions stays running forever, just as 
described before.

"filetocompress.txt" is just a typical text database file of names, addresses, 
etc.
with one alphanumeric line per tuple.

Test code on my Ubuntu 9.10  Machine is working perfectly

Maybe you want to try the latest TRUNK version from SVN as it contains a new 
"in-memory" approach (courtesy of Jean-Luc Cooke) instead of the tmpZipFile 
that was used before (and is still available, if you need to process huge 
amounts of data).

as there was no answer on the latest solution proposal one and I can't 
reproduce the issue, I'll take the liberty to "ivalidate" it
