Vera Straube commented on FOP-2857:
-----------------------------------

We use the fop as part of a webapp in a tomcat webserver. The tomcat starts as 
service under windows and is not a "real" user with his own home dir.

> FontCache.toDirectory() and FontCache.getDefaultCacheFile() work not correct

> The function getDefaultCacheFile() of the class FontCache should work like 
> this:
> [1] case:       select user_dir
> -> user_dir:    'C:\Users\strv'
> -> temp_dir:    'C:\Users\strv\AppData\Local\Temp\'
> -> cache_file:  'C:\Users\strv\.fop\fop-fonts.cache'
> [2] case:       select temp_dir
> -> user_dir:    ''
> -> temp_dir:    'C:\Users\strv\AppData\Local\Temp\'
> -> cache_file:  'C:\Users\strv\AppData\Local\Temp\.fop\fop-fonts.cache'
> [3] case:       select curr_dir
> -> user_dir:    ''
> -> temp_dir:    ''
> -> cache_file:  'fop-fonts.cache'
> Actually it works uncorrectly like this:
> [1] case:       select user_dir
> -> user_dir:    'C:\Users\strv'
> -> temp_dir:    'C:\Users\strv\AppData\Local\Temp\'
> -> cache_file:  'C:\Users\strv\.fop\fop-fonts.cache'
> [2] case:       select temp_dir
> -> user_dir:    ''
> -> temp_dir:    'C:\Users\strv\AppData\Local\Temp\'
> -> cache_file:  '.fop'  --> wrong behavior !!!
> [3] case:       select curr_dir
> -> user_dir:    ''
> -> temp_dir:    ''
> -> cache_file:  '.fop'  --> wrong behavior !!!
