The JSR 14 download uses the following line, in a batch file, to substitute in a different javac .class file when compiling.
how can ant be made to use the new compiler of jsr14 for all <javac tags? This wont be an issue after j2se1.5 is released. Ant allows specification of wich compiler via build.compiler property but there is no value for 1.5 or the early release patch for jsr14
