JDK 6

javap no longer finds classes on the extension classpath. This used to work in earlier releases and in Mustang up to b54 but not in more recent builds:

EVALUATION This is not a regression but a long existing problem in javap. If the extension classpath contains multiple entries, javap cannot handle it correctly. It causes the regression when the extension mechanism was changed to make the default classpath contain two entries.

SUGGESTED FIX Diffs: ------- JavapEnvironment.java ------- 218,219c218,220 < resolveExdirFilenamehelper(path, classname); < --- > InputStream in = resolveExdirFilenamehelper(path, classname); > if (in != null) > return in; In context: public InputStream resolveExdirFilename(String classname){ if(classpath.indexOf(File.pathSeparator) != -1){ //separates path StringTokenizer st = new StringTokenizer(classpath, File.pathSeparat or); while(st.hasMoreTokens()){ String path = st.nextToken(); InputStream in = resolveExdirFilenamehelper(path, classname); if (in != null) return in; } }else return (resolveExdirFilenamehelper(classpath, classname)); return null; }
