See http://java.sun.com/j2se/1.4/docs/guide/lang/assert.html One impact of this is that methods named "assert" will be flagged as a compilation error. The jakarta-log4j project simply chose to remove such a method. I see that such a method is defined by httpclient - but I see no real usages. So one fix might be to simply remove the method. Another would be to replace the call to log4j's assert with the following: if (!assertion) _category.error(msg); - Sam Ruby
