Jclic hangs on exit with openjdk

Bug Description

In every Ubuntu version from 10.04 to 12.04, tried on several machines.

Package installed:
* jclic
* openjdk

Jclic works perfectly until I try to close it, the application hangs and the only way to terminate it is going on a terminal and kill the java process.

Workaround until 12.04:

Installing the sun-java6-jdk and with update-alternatives make it the default jdk

Workaround modification in 12.04:

Since the sun jre is no longer distributable with Ubuntu, I had to install the Oracle jdk.
I decide to use a ppa to mantain the package updated easily so I use these commands:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
The script also provide to make the new jdk the default one.
When launching jclic nothing happens so I launch it from a terminal and I discovered that it couldn't find the jdk because it was searching it in the wrong path (error in line 36).

So I had to modify the script /usr/bin/jclic this way:

if [ -z $JAVA_HOME ] ; then
 ALTERNATIVE=`ls -l /etc/alternatives/java|grep sun`
 if [ -z "$ALTERNATIVE" ]; then
  ALTERNATIVE=`ls -l /etc/alternatives/java|grep openjdk`

 if [ -z "$ALTERNATIVE" ]; then
         t=/usr/lib/jvm/java-1.5.0-sun && test -d $t && JAVA_HOME=$t
         t=/usr/lib/jvm/java-6-sun && test -d $t && JAVA_HOME=$t
         t=/usr/lib/jvm/java-7-icedtea && test -d $t && JAVA_HOME=$t
# lines added
        if [ -z "$ALTERNATIVE" ]; then
         t=/usr/lib/jvm/java-7-oracle && test -d $t && JAVA_HOME=$t
# end added lines

Now Jclic works fine but I know that an update will remove my lines, is it possibile to fix jclic to work with openjdk or to link the correct path for java-7-oracle?
