Wouldn't it be better to have one installed version rather than several? I recieved an update to java today, making my total installed updates 11.
J2SE runtime environment 5.0 update 10145 MB
J2SE runtime environment 5.0 update 11146 MB
J2SE runtime environment 5.0 update 2 117 MB
J2SE runtime environment 5.0 update 3 143 MB
J2SE runtime environment 5.0 update 4 118 MB
J2SE runtime environment 5.0 update 6 119 MB
J2SE runtime environment 5.0 update 8 145 MB
J2SE runtime environment 5.0 update 9 145 MB
Java 2 runtime environment, SE v1.4.2_03135 MB
Java 2 runtime environment, SE v1.4.2_06108 MB
Java(TM) SE runtime environment 6 update 1 159 MB
Doesn't this seem a little much?
Each update is cumulative of all bug fixes to date. However, application vendors
can specify which specific version that their app needs. So this isn't a problem
with your update, or the version of JRE you just installed. It's an issue with
application vendor hardcoding the version of JRE they need. This is why you
need to be careful about removing older versions.
Here's a more detail readup:

(read first question)
And if you evern need older version, read later question about how to obtain
those.
Hope this helps.
