A clean-room implementation is not a "legal maneuver"

Authored by: Anonymous on Tuesday, May 22 2012 @ 06:30 PM EDT

> Google used Dalvik because it is better-suited,
performance-wise, to use on a restricted memory, low-power
CPU device.

Yes, but those would be older-generation feature phones. Not
smartphones. Oracle's Java SE embedded Hotspot JVM
outperforms Dalvik by a big margin.

> Apache Harmony is not certified by the Sun TCK because of
the field-of-use restrictions. Apache was actively
campaigning for Sun...

True, and that's the reason Android is not officially Java.
However, unlike the APIs whose copyrightability is in
dispute, the JVM spec is explicitely licensed only to TCK
compliant implementations, and that's why Google were forced
to use Dalvik, which does not follow the spec. This is a
legal maneuver.
