the JRE?It is the SDK that is important and it is not distributed because you need permission (signed agreement) from Sun, you need to pay. Remember that Linux is the cause to that Sun soon is out of business. Also the Linux Java version is not made by Sun.
I don't mean to be picky, but since you are partially correct, I guess I should point out which parts are correct and which are not.
the JRE?It is the SDK that is important
Yes, to developers it is the SDK that is important.
However, to Joe User, the JRE is the JVM that Joe was asking about.
it is not distributed because you need permission (signed agreement) from Sun
I checked the Java SDK license agreement, and it would not allow a distro to include the Java SDK.
Any developer, on the other hand, that develops a Java application can ship the Java SDK with that Java application (for free) for the purpose of running said application.
you need permission (signed agreement) from Sun, you need to pay
I do not know if you need to pay or not. You'd have to ask Sun. The Java SDKs are free to download; I highly doubt that Sun charges for them to be included in distros, but obviously I could be wrong.
Remember that Linux is the cause to that Sun soon is out of business.
Sun is doing fine for a server hardware vendor. Their main problem is that IBM has been spanking them pretty severely on the high end and Dell has been spanking them pretty severely on the low end.
On the other hand, Sun is doing much better now on the low end, due to AMD Opteron-based servers (Sun sells more Opterons than any other company) and a combination of Solaris for x86 and Linux.
On the high end, I doubt that Sun will ever be a performance leader, although they've always done OK when it comes to price/performance (only because IBM is ridiculously expensive on the high end).
Also the Linux Java version is not made by Sun.
That's new news to me. For years, the Java SDK for Linux has been made by Sun.
FWIW - My guess is that you are referring to Blackdown, which is now based on Sun's Java SDK and not vice versa.
