I think we have a regression that I and others have run across.  
I don't think we would be allowed to fix this in 1.4.2, but
I would like to document any workaround in 1.4.2.

Running javadoc on a typical source file, CustomTags.java works just 
fine.  This source file has no package statement and so can be properly 
placed in any directory.

The problem is when another source file, Class1.java, is added to the 
directory holding CustomTags.java -- then an InvocationTargetException
is thrown.  There seem to be two conditions that must be met for
this error to be thrown:
 - Class1.java must be linked to from CustomTags.java, which it is 
   with "@see Class1", and
 - Class1.java must not be in a directory that corresponds to its package
   statement, in this case "package com.package1".

Here, I run javadoc on CustomTags.java without Class1.java present:

% cd ~/javadoc/1.4/bug-4835749-invocationtargetexception
% ls -F

% more run
/jdk/1.4.2/latest/binaries/solaris-sparc/bin/javadoc -d html CustomTags.java

% run

This works fine, generating docs as expected.

But if I move a source file Class1.java that CustomTags.java links
to (with @see Class1) into the current directory, then I get an
InvocationTargetException with bad class file ./Class1.java:

% mv dir/Class1.java .

% run

1 error

The error does not occur if "@see Class1.java" is removed from

This is a regression, because when using javadoc 1.3.1, this example
runs fine with no error.  

Oddly, if you pass the *invalid* Class1.java into javadoc, it is
documented just fine with no warnings or errors, if passed in as a
.java file (rather thana package name):

   javadoc Class1.java

CONVERTED DATA BugTraq+ Release Management Values COMMIT TO FIX: tiger tiger-beta FIXED IN: tiger-beta INTEGRATED IN: tiger-b32 tiger-beta

PUBLIC COMMENTS This bug has been fixed in 1.5.0.

EVALUATION ###@###.### wrote (to paraphrase) 2003-03-24: This is not a bug. Javadoc is being exposed to a bad file in its source path so it complains. Class1.java is invalid because it belongs in package com.package1, but it is not in the appropriate package. It is sitting in directory bug-4835749-invocationtargetexception, which is not right. Class1.java is attempted to be loaded because CustomTags.java links to Class1.java with an @see tag. If you remove the package statement in Class1.java, the error goes away and it runs fine. Or if you move Class1.java to com/package1/Class1.java, the error goes away. However, keep in mind this exception is not thrown in 1.3.1. Is this a regression we should fix, or is it proper to throw the exception? If the latter case, -- can we please change the error message to something more helpful, such as: com.package.Class1 not found in directory com/package1 off sourcepath ###@###.### 2003-04-24 Changed synopsis from: InvocationTargetException when generating doc w/ other .java file in current dir to: InvocationTargetException when src file links to another src file in wrong dir ====================== This bug has actually been fixed in 1.5.0. I added a regression test to verify this. ###@###.### 2003-12-01
