GWT 2.8 generates code 14% bigger than GWT 2.7

Hi.

We are trying to move our website from GWT 2.7 to 2.8 but we have found that GWT 2.8 generates code which is significantly heavier.

For example, these are the sizes for one of the permutations:
GWT 2.7 + Closure Compiler:  590 KB
GWT 2.7 without Closure Compiler:  664 KB
GWT 2.8 (no Closure Compiler available):  674 KB

So the difference between 2.7 and 2.8 is +14% code size.

We would like to keep our site up to date with the last version of GWT but we don't like increasing our website code in this manner because it means higher downloads, higher waiting times, worse user experience, etc.

Do you plan to bring Closure Compiler (-XenableClosureCompiler option) back to GWT? It was very useful for us.

Kind regards,
Oscar
