Subject Re: JEX wants to play in the sandbox - license issue
Date Wed, 12 Jun 2002 13:35:27 GMT
Before I drop it in the sandbox, I want to make sure it is ok that JEX
depends on Rhino, which is under a license that is a combination of
GPL, LGPL and MPL.  I read the parts of that license I could understand
and it appears to be ok to include JS.jar wholesale without infecting
Apache with GPL, but I am not a lawyer, so I cannot be absolutely sure.

Could somebody clarify this license issue, please.
