Subject Re: [VOTE] Release Apache TubeMQ (Incubating) 0.8.0-incubating RC2
Date Thu, 18 Feb 2021 22:59:58 GMT
Which Oracle product is TubeMQ dependent on?

From what I see, there are two distinct Oracle products, with different licenses:

Berkeley DB uses a Category X non-commercial license, which Justin points out is not an open
source license.

Berkeley DB Java Edition uses a standard Apache License, v2.0 with an additional license that
appears to be the 3-clause BSD license for an embedded third-party component; both of which
are Category A licenses.

So if the project uses only Berkeley DB Java Edition, all is well. If it uses Berkeley DB
then we have a problem.
