Fair enough.

After learning a bit more about this feature, I'm thinking of removing
it entirely.

java -Xshare:dump only works with the "client" jvm.

It seems a "client" jvm is some form of optimization for low-performance
machines: it only exists for 32-bit systems, and is only enabled if
there's only one CPU and less than 2 GB of memory (or if one forces its
activation with the -client switch).

It would be useless on most machines people may want to run Java on...

Comments, anyone ?
