bug#11254: 24.0.94; cannot find compilation-error locations for Java

[Sam Steingold]

When I work on a maven-managed java project, I add this to
java-mode-hook:
(set (make-local-variable 'compile-command)
     (concat "cd " (locate-dominating-file buffer-file-name "pom.xml") " && mvn 
compile test package"))
i.e., M-x compile RET runs maven in a directory far above the location
of the current file.
The errors in the compilation buffer look like this:

java.io.FileNotFoundException: null (No such file or directory)

where every single line in clickable in the most useless way possible:
it asks _me_ for a directory where the file in (file.java:lineno) is located.
Note that most error lines (e.g., org.apache.*) are _not_ in my tree at
all, so making them clickable is a waste and a source of confusion.
Also, note that the method name contains the directory path to the file
(with "/" replaced with "." and some prefix like "main/java" missing).

PROPOSAL:

1. new user variable `compilation-my-methods-regexp', which, when
non-nil, prevents all other methods from being clickable.

2. new user variable `compilation-other-methods-regexp', which, when
non-nil, prevents the specified methods from being clickable.

3. when I click on a line in the stack trace, find(1) is run in the
`default-directory' of the compilation buffer like this:
if I click on
"org.codehaus.classworlds.Launcher.launch(Launcher.java:255)"
`find . -path org/codehaus/classworlds/Launcher.java`
and if that finds a single file, then that file is visited at the
specified line, and if more than one file is found, a find-dired is
run.


PS. I am using JDEE, and it delegates error finding to the stock emacs 
facilities.
