- xbeta 9y agoI was intern'd at IBM Toronto Lab about 10+ yrs ago to add instruction sets for this compiler/JVM. It was fucking awesome experience back then!
- kodablah 9y agoWill they now be denied to use the TCK going forward like Harmony was? If not, why? Because they were proprietary first? Because Oracle likes the Eclipse license better than the Apache one? Oracle has stated that for open source, only OpenJDK derivatives get access to the TCK.

- filereaper 9y agoThere's some mythology here, perhaps another J9 greybeard can answer. The story I've heard so far goes as follows... There was some constant for 8K that was mistyped incorrectly, something like instead of: #define 8K 8192 They mistyped and wrote: #define 8K 8096 This caused all sorts of bugs and was known internally as the 8K bug. When time came to write the Java VM, they wanted to name it as "post 8k bug" they named it K9, but K9 sounds like a dog (woof) so they decremented the K to land on J9. At least that's what I've heard... shrugs
- rservant 9y agoThis close, but not right. Dogs never entered into the equation. I'll post a blog somewhere with the history and come back here with a link.
