> beta15 breaks GAE & some other prod environments
> I have a couple of app engine apps that are broken w/ beta15
> This is due to use of java.io.File to mkdir, which is prohibited on app engine and is more generally considered a JEE no-no.
> ...
> ResourceTransformerFactoryImpl creates a File for the asset cache directory.
> This breaks my app in GAE, since creating a new File is prohibited.
> ...
> it looks like the cache is only used in development
> mode but still references File in production (thus breaking GAE). Perhaps a
> proper fix will involve a pluggable cache which does nothing in production
> mode.
> As a workaround you can override the ResourceTransformerFactory via ioc
> with an implementation that doesn't reference java.io.File. Most likely a
> copy/paste/tweak of the current version.
> ...
> Note, this could also break non GAE environments since it calls mkdirs() on
> @Symbol(WebResourcesSymbols.CACHE_DIR). For example a unix server without
> write permission.
