For everyone, who's still interested in the solution:
It happens to be a problem with the os:

Re: SecureRandom on Linux

I ran into the same problem with JDK 1.4.1_01 and JDK 1.4.2_05 running on
Redhat Linux using kernel 2.4.9.
After running the issue in the debugger for a while, I found it was always
hanging on a read in a native method while trying to generate a secure seed in
sun.security.provider.SeedGenerator which is called from
sun.security.provider.SecureRandom. I got this error whether I was calling
SecureRandom directly, or whether it was just used by the SSL libraries in
setting up a secure SSL connection with a server. See below for a stack trace
of where it was hanging.
The problem seemed to be that the security provider used /dev/random as an
entropy generator, and it somehow wasn't working. By editing the
$JAVA_HOME/jre/lib/security/java.security file and changing the property:
securerandom.source=file:/dev/random
to:
securerandom.source=file:/dev/urandom
the problem disappeared for me. So there seems to be some issue with the OS
access to /dev/random. Hope this helps with your issue.
