Description

The test opennlp.tools.cmdline.ArgumentParserTest.testSimpleArgumentsUsage() is failing here. Is it happening to anyone else?
I checked the ArgumentParser class. The method createUsage(Class<T> argProxyInterface) works by getting the methods of the argProxyInterface class using the getMethods() method.
The javadoc of getMethods() method says: "... The elements in the array returned are not sorted and are not in any particular order. ...".
So we can't expect the usage string to be the same to everybody. To me it is "[-iterations num] [-alphaNumOpt true|false] -encoding charset", but the expected is "-encoding charset [-iterations num] [-alphaNumOpt true|false]", so my build fails.
