Doppio doesn't work with upstream javac

[jvilk]

1. Grab a bzip of upstream javac here: http://hg.openjdk.java.net/jdk6/jdk6/langtools/archive/tip.tar.bz2
2. Compile all of the *.java files. I do this like so (from the src/share/classes folder):

export JVC_CLASSES=`find . -name *.java | tr '\n' ' '
javac $JVC_CLASSES

1. Try to invoke com/sun/tools/javac/Main on something. You will get the following result:

Internal JVM Error: TypeError: Cannot call method 'toClassString' of undefined

I did a quick debug print; this is the value of obj (it tries to do obj.type.toClassString()) when this occurs:

{ '$first': null,
  'com/sun/tools/javac/util/BaseFileManager': null }

Looks like a field is being used instead of the actual object?

My repro with the current head (xargs is better than your tr hack):

src/share/classes$ find . -name *.java | xargs javac
Note: ./com/sun/tools/javadoc/Messager.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

doppio$ ./console/runner.coffee --classpath=/tmp/langtools-4ab5d66aaf2b/src/share/classes/ com/sun/tools/javac/Main --java=classes/demo/Fib.java
doppio$ java classes/demo/Fib
fib(20) = 6765

Disposition: works for me. Closing.
