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
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
