John May told me that it only depends on J7, but maybe one of the CDK
dependencies now depends on J8?

No, more like 25MB :)

Ah... well, it's mostly dependencies that increase the size.

BioC developers, would rcdk be welcome on BioConductor? It's
frequently used in biology, e.g. metabolomics.

Rajarshi, Zach, would you consider that if the size issue becomes an issue?

Alternative, the whole CDK modularization has the purpose of being
able to reduce the size of the needed libs. We could look and see
which CDK modules are actually used by rcdk and then not depend on the
full CDK but only on the modules it really needs.

That only makes sense of you put the CDK dependencies in rcdk-libs, or
possible split up in three versions, because the 3rd party libs the
CDK depends on are more stable than the CDK, which has releases every
half year or so at this moment. I think if you put the 3rd party lib
jars in rcdk-libs and the CDK jars in rcdk itself, you may still be
below the 5MB...

Yes, I know this issue, which I had with the rrdf package too. (BioC
developers, would that package be welcome on BioConductor?)
