Failed for me using Fedora Core 5, sun JDK 1.5_08
I don't think its javac as I was able to do this:
touch src/test/Test3.java
javac -d bin -sourcepath src -classpath bin src/test/Test3.java
That worked me as well, however I modifed the build script
to do this:
<javac source="1.5" target="1.5"
srcdir="src" destdir="build/classes"
includeantruntime="no"
debug="yes" fork="yes" executable="${java.home}/../bin/javac.exe"/>
and ran ant with -debug to see the exact command line:
"c:\program files\java\jdk1.6.0\jre\..\bin\javac.exe" -d "C:\Documents
and Settings\reilly\learning\a\compile\build\classes" -classpath
"C:\Documents and Settings\reilly\learning\a\compile\build\classes"
-sourcepath "C:\Documents and Settings\reilly\learning\a\compile\src"
-target 1.5 -g -source 1.5 "C:\Documents and
Settings\reilly\learning\a\compile\src\org\test\Test3.java"
This failed as well.
I removed the differences one at a time, when -classpath was removed,
the problem
went away.
I think that this is a javac problem, but perhaps ant does not need to set the
classpath attribute when -d is the same as -classpath ?

Javac seems to find everything correctly...but the javac task in ant is
having difficulties. One thing to note is that the generics referred to
by the inner classes are defined in terms of the outer class.
