After trying to upgrade Grails to Groovy 2.4.6 there are numerous problems with @CompileStatic and type inference with Maps and Lists. If I had seen the vote for the release in time I would have tested and voted -1, so sorry for only reporting this afterwards. This commits shows the changes I had to make in order to get Grails to compile with Groovy 2.4.6: https://github.com/grails/grails-core/commit/a6d70aaf7925fb7f2e847a803a8e1f3c95bf8cf8 You can see for example that previously returning a list initialised with variables of the correct type compiled, but no longer does: https://github.com/grails/grails-core/commit/a6d70aaf7925fb7f2e847a803a8e1f3c95bf8cf8#diff-3092a650525dc131a0394eca4282362bL35 Also empty lists and maps no longer seem to compile.
