The licensing is little complex. The original author - Claus Gittinger made it available for personal and commercial use for free. The source is available and you can change it (I do it a lot) but not the VM and STC (Smalltalk/X AOT compiler). For this, you may want to contact Claus Gittinger for special arrangement.
Now, Smalltalk/X jv-branch is a "fork" that I'm maintaining and developing. All the code I have written is open source, some LGPL, some MIT, some CCNC. All my changes to the VM and STC are opensource (license-wise) but I cannot make them public unless I rewrite 100% of the code from scratch :-)
I understand this is a bit complex and hard to understand. I should write some text explaining this in more detail...
