Compiling the enhancer sources with JDK 1.5 on a fresh checkout on Solaris, two warnings were reported by javac, which I don't think having seen before:
/export/martin/jdo/apache/jdo/trunk/ri11/src/java/org/apache/jdo/impl/enhancer/core/Augmenter.java:71: warning: unmappable character for encoding ASCII // attribute in the attributes table of a Code (?4.7.3) ^ /export/martin/jdo/apache/jdo/trunk/ri11/src/java/org/apache/jdo/impl/enhancer/ClassFileEnhancerHelper.java:63: warning: unmappable character for encoding ASCII * The output stream has the same compress?on (if any) as the input ^ The two source files had indeed unprintable characters there, which I fixed and checked in.
