single quote in the application properties file don't works on Struts like any other java app?

[Matteo Di Giovinazzo]

When I want to insert a single quote, I write in the properties file's
key " \' " (traditional escaping) to obtain a single quote as output. Indeed
I obtain that the single quote disappear. Using the '' (double single quote
escaping) my file don't works with any other java app (a not-Struts app,
like swin, awt or console...)

My main question is: this works fine on all other java application, why not
with Struts? Where is the problem?
