Bug ID: 54298
Summary: more efficient (and shorter) method calls in
FTPTaskMirrorImpl.makeRemoteDir
Product: Ant
Version: 1.8.4
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Core

patch
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 "FTPTaskMirrorImpl.makeRemoteDir", there are two calls to
"dir.indexOf("/") == 0". These calls should be "dir.startsWith("/")".
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 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.
I attached a second one-line patch (secondCall.diff) for the second
call.
