Your likely one of the few to do that :) |

| 11 |
That is good one does not have to go back to 1.5, and 1.6.. Not bad to |
| 12 |
get to 1.8, but once 9 is out. Not much fun going from 7 to 8 to 9. |
| 13 |
No real reason to do that unless you want to. Or don't trust |
| 14 |
Chewi/James icedtea-bin. He does like to spy :P j/k |
| 15 |

| 16 |
The main reason for icedtea/openjdk vs oracle is to build openjdk or |
| 17 |
java with open source licenses. I think if you build against oracle |
| 18 |
your accepting oracles license for their JDK. It does not really taint |
| 19 |
the result. But does mean java was built with non FOSS software. Oracle |
| 20 |
JDK is downloaded under a different license agreement. |
| 21 |
|
| 22 |
Its mostly a legal thing, and there is some slightly better system |
| 23 |
integration. Definitely if building from source. Still some using |
| 24 |
icedtea-bin, but thats a binary. So not sure as deps it was built |
| 25 |
against change, etc. From source is likely different there. |
| 26 |
Though I haven't really ever had issues with Oracle and system |
| 27 |
integration. Occasionally people will have fonts issues. Fonts tends to |
| 28 |
be one of the most noticeable visual difference between Oracle and |
| 29 |
Icedtea/OpenJDK |
| 30 |
|
| 31 |
I do not mess with openjdk/icedtea much if at all. I mostly run with |
| 32 |
Oracle for various reasons. Licensing is not a concern. I am used to |
| 33 |
Java long before it was FOSS. |

The main problem with arch support is HotSpot. There is not many |
| 39 |
replacements for other archs. |

Not sure of OpenJ9 will change that. I think it will at min support |
| 43 |
Power archs, ppc64 etc. Not sure about ppc 32bit. |

Otherwise yes, unless icedtea-bin exist for that arch. Boostrapping |
| 49 |
in a post gcc-jdk/java 7 world will be difficult, If not impossible for |
| 50 |
some archs. |
