tDoclet.java:128)
This happens when generating the serialized form.  For every package, we call
PackageDoc.allClasses(false) to search for serializable classes.  I put a debug
statement that prints "****FATAL <qualified class name>" to find out which
ClassDocs are causing the null pointer.  I am seeing weird names like
java.util.AbstractMap$1 and java.util.Collections$1....  I am just
trying to generate headings like "java.util.ArrayList extends AbstractList".

Examples of the null pointer are below.  You can see the full J2SE doc build log

Comments

EVALUATION The "weird" class names indicate anonymous inner classes. There are 10 of these (AbstractMap$1 - 4 and Collections$1 - 6). Are they the only ones causing problems, or are there others? These 10 classes are returning true for isSerializable(), even though they are not serializable. And they're throwing NPE when you ask for their supertypes, as you've seen. ###@###.### 2003-09-16 Given the symbol for one of these anonymous classes, type.supertype() is returning NULL. One symptom of this is that ClassDocImpl.isSerializable() returns true when it shouldn't, and another is that ClassDocImpl.superclassType() throws NPE. It looks like the class symbol is being accessed by the doclet before being completed. How can that happen? ###@###.### 2003-09-16 I wrote a test that verifies this bug was fixed in build 24. Here is the test: import com.sun.javadoc.*; public class SuperTest extends Doclet { public static boolean start(RootDoc root) { PackageDoc[] packages = root.specifiedPackages(); for (int i =0; i < packages.length; i++) { ClassDoc[] classes = packages[i].allClasses(false); for (int j =0; j < classes.length; j++) { System.out.println("Processing " + classes[j].qualifiedName()); classes[j].superclassType(); } } return true; } } Here is the test output: /net/koori.sfbay/onestop/jdk/1.5.0/promoted/beta/b23/binaries/solaris-sparc/bin/javadoc -docletpath . -doclet SuperTest -sourcepath ~/j2se/src/share/classes/ -source 1.5 java.util Loading source files for package java.util...

###@###.### 2003-12-28 Due to an unrelated bug fix, classes whose names contain characters not allowed in Java identifiers are no longer "included". Thus this error is no longer encountered. The workaround in the standard doclet can probably be removed. ###@###.### 2004-01-09 Note that for a time during Tiger development, anonymous classes were named with '+' characters rather than '$'. When this change was undone, it appears that some of the old problems resurfaced. Bogus entries returned to the serialized-form.html page before Beta 2 shipped. ###@###.### 2004-11-20 05:38:38 GMT

WORK AROUND If a class is not "included", and asking for its supertype results in NPE, then don't generate any serialization info at all for that class (assume that isSerializable() is returning bogus info) and just move on. ###@###.### 2003-09-16
