+ Overview Description
+ 
+ The rmic core task has a 'sourcebase' option which passes
+ the '-keepgenerated' option to rmic. It also moves the
+ generated source to a directory of your choice.
+ 
+ If you want to keep the generated source in the same place
+ as the stubs & skels (ie, sourcebase=base), Ant will
+ delete the generated source when rmic completes.
+ 
+ Steps to reproduce
+ 
+ <rmic base="directory"
+       sourcebase="directory"
+       classname="com.ClassFile" />
+ 
+ or even
+ 
+     <rmic base="."
+           sourcebase="."
+           classname="com.ClassFile" />
+ 
+ Actual Results
+ 
+ Run Ant - while rmic is executing, you can see the generated .java
+ files appear with the .classes. When rmic completes, the .java files
+ disappear. (If rmic completes quickly you may miss the .java files).
+ 
+ Expected Results
+ 
+ The .java generated source in the same place as the stubs & skels.
+ If sourcebase!=base, Ant corrently moves and preserves the generated
+ source.
+ 
+ What appears to be happening
+ 
+ The method org.apache.tools.ant.taskdefs.Rmic.moveGeneratedFile()
+ first copies the file to the new location, then deletes the old
+ copy. This strategy fails if the destination is the same as the
+ source directory.
+ 
+ Suggested fixes
+ 
+ 1) Make moveGeneratedFile() check if the baseDir and sourceBaseFile
+    parameters are equivalent. If they are, return without doing the
+    move. I'm not sure if Ant processes '../../' type relative dirs,
+    so it may not be a simply compare (although that would help).
+ 
+ 2) Add a separate 'keepgenerated' option to the rmic core task that
+    doesn't try to move the files after generation.
