Quitting javac task with CTRL-C can leave temporary files

           Summary: Quitting javac task with CTRL-C can leave temporary
                    files
           Product: Ant
           Version: 1.6Alpha (nightly)
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core
        AssignedTo: dev@ant.apache.org
        ReportedBy: marc@kenamea.com


When compiling a large number of classes at once, it appears that when
Ant is configured to use jikes it will create a temporary file called
"filexxxx" or "file-xxxx" where xxxx is some random number.  The
temporary file contains a list of all the java files being compiled.  It
then removes this file when the jikes is complete.  However, if the
compile is interrupted (such as hitting CTRL-C when a long list of
compile errors is being spewed back), it will fail to delete the
temporary file.  If I switch the compiler to "javac" it doesn't appear
to create any temporary file.

I have created a fix for this based on the current CVS code.  This fix includes 
a new method to FileUtils called deleteOnExit(...) which uses reflection to 
determine if JDK1.2+ is being used and if so, calls File.deleteOnExit() on the 
file passed in as a parameter.  The patch calls this new method in the 
DefaultCompilerAdapter class when a temporary file is created.  The patch seems 
to get rid of this problem.
