      Description

      I am experiencing URL hangs on SOLARIS 2.6 with the latest JDK1.2FCS-G
      build. This is probably all related to the TCP bug I put in namely bugid
      4168586. Below is an invocation of a URL program called GetURLInfo which
      has a stack trace of the hang.

      The GetURLInfo program is part of the attachment. To invoke the GetURLInfo
      program type the following in a loop. It may take awhile before the hang
      will occur but it will eventually occur.

      % sh
      % while true
      > do
      > java -Djava.compiler=none -DproxyHost=webcache.east.sun.com -DproxyPort=8080 -Dftp.proxyHost=webcache.east.sun.com -Dftp.proxyPort=8080 GetURLInfo -d -v -f data/GetURLInfo.data -o results/outgeturlinfo
      > done

      To extract the GetURLInfo program type:

      % uncompress url.tar.Z
      % tar xvf url.tar
      % cd url

      To run the GetURLInfo program type:

      You will need to set -DproxyHost and -Dftp.proxyHost to your correct server.

      % java -Djava.compiler=none -DproxyHost=webcache.east.sun.com -DproxyPort=8080 -Dftp.proxyHost=webcache.east.sun.com -Dftp.proxyPort=8080 GetURLInfo -d -v -f data/GetURLInfo.data -o results/outgeturlinfo
