firstCall.diff

The problem appears in version 1.8.4 and in revision 1421898.  I
attached a one-line patch (firstCall.diff) that fixes it.

In method "XmlPropertyTest.ensureProperties", the call
"propertyValue.indexOf("ID.") == 0" should be
"propertyValue.startsWith("ID.")".  The intent of the call is more
explicit with "startsWith" than with "indexOf(..) == 0".  "startsWith"
is also more efficient than "indexOf", because "startsWith" tries to
match only the start of the string, while "indexOf" searches until the
first occurrence.

There is a similar second call to "propertyValue.indexOf("FILE.") == 0".  
I attached a second patch (secondCall.diff) for it.

There are many calls to "String.startsWith" in Ant (just like in the
proposed patch), for example, in methods "AntlibDefinition.setURI",
"AntClassLoader.isParentFirst", "ComponentHelper.checkNamespace",
"Execute.getVMSLogicals", "ExecTask.isPath", "Jar.writeIndexLikeList",
"Definer.makeResourceFromURI", "PathTokenizer.nextToken", etc.
