May I suggest to add this method to the org.apache.fop.hyphenation.Hyphenator
class?
I had to hack FOP and create a custom build for myself, because I need to
reload the hyphenation files at runtime.
The use case is, that I have a web applications that allows on an admin page,
to add hyphenation exceptions on-the-fly. In that case the hyphenation pattern
files are re-created with the new exceptions but need to be reloaded by FOP.
The below worked for me, please consider adding to the trunk.
Best,
Marc
/**
* Clear the hyphenation tree cache, in case the underlying data files have
changed at runtime.

public static synchronized void clearHyphenationTreeCache() {
hTreeCache = new HyphenationTreeCache();
}
