> Key: EASYANT-75

> Project: EasyAnt
> Issue Type: Bug

> Labels: compliance

> When running EasyAnt with J2SE 1.7, calling
> {{EasyAntEngine.guessEasyantCoreJarUrl()}} raises a
> {{NoSuchMethodException}}/{{IllegalArgumentException}}.
> *Code to fix:*
> {{EasyAntEngine.getLocalURL = conn.getClass().getMethod("getLocalURL",
> (Class<?>) null)}}
> {{URL localJarUrl = (URL) getLocalURL.invoke(conn, (Class<?>) null)}}
> *Fixed code:*
> {{EasyAntEngine.getLocalURL = conn.getClass().getMethod("getLocalURL", null)}}
> {{URL localJarUrl = (URL) getLocalURL.invoke(conn, null)}}
> *Reason:*
> From JES2 1.7 Javadoc, calling {{getMethod}} or {{invoke}} with no varArg or
> a {{null}} varArg is treated as if the method was called with an empty array
> (compliance with JES2 1.5).
> But calling those methods with a {{null}} varArg that is casted to
> {{Class<?>}} is treated as an array of {{Class<?>}} that contains one
> {{null}} element. So there is no matching method, hence the
> {{NoSuchMethodException}}/{{IllegalArgumentException}}.
