Another java question

[Jim Byrnes]

Earlier today I asked about a problem running a java streaming stock 
qoute app on my brokers web site after a java update came through.  As a 
test I tried the site using my laptop running Saucy, which had not been 
updated in a couple of days.  I got the same error I encountered on my 
desktop running Precise.

I installed java on both machines from LP-PPA-webupd8team-java.  Looking 
at Synaptic on the Saucy laptop I see I have java 8 on it.  This 
surprised because the update I just installed on my Precise desktop was 
to Java 7.  Looking at Synaptic on the desktop shows 
oracle-java7-installer as the installed version, but 
oracle-java8-installer is listed.

I'm not sure how this could happen and if I mark it for installation 
will it then proceed to install java8?

Of course this is not the source of the problem with running the java 
app on the web site, but I would like to get it fixed before calling 
their tech support.

Thanks,  Jim
