jdk16 does not allow to connect to socket

[ken]

  Dear all,
  It might be a stupid question...

  Recent update to 7.2 release and reinstallation of jdk16/openjdk6 disabled me to connect to through sockets/ports - svn in eclipse is not usable, while I can connect to with diablo-jdk1.6.0.
  I rewrote /usr/local/{jdk1.6.0,openjdk6}/jre/lib/security/java.policy, but it seems that it is not reflected.

  What am I wrong?
