--------------------------------------------------------
I'm waiting for a 5 minutes and no exceptions are thrown.
Sorry, I made a mistake identifying the bad method.
I run the application under debugger and found the really bad method.
It is ActionConfigMatcher.convertParam(String val, Map vars). It has an
infinite loop at line 262 (struts-1.3.9).
In my case the parameters passed into method are:
val = "{1}"
vars = "1->{0}, 0->page-{0}"
So, there is an infinite loop while replacing all instances of the
placeholoder, because the placeholder wildcard looks like exact value.
