| Eclipse crash/busy-loops on Javadoc generation [message #511916] |

I had the odd effect today that eclipse (Galileo) kept going into some busy
loop whenever I edited a specific java file. I boiled that down to the
Javadoc generation and carved out the below example.
Whenever I open that class in the editor and go into the getStyleSheet()
method and the Javadoc-view/tab is currently selected my eclipse gets
unresponsive and hangs in some busy loop from which I can only kill it via
task manager.
I didn't want to spend even more time on this and so I didn't reduce the
comment to the actual culprit, but the below should make it easy enough to
reproduce the issue and then search and fix the problem.
Where to report?

package test;

public class Test
{
static final String cssName = "css/someName.css";
/**
* @return the URL from where to read the style sheet
*
* Note: The search algorithm for resources in applets is completely
brain-damaged:
* In contrast to java applications, for applets a resource must be
available NOT
* relative to the class (as one would expect) and thus also not IN the
..jar file
* containing the applet's code, but as an individual file relative to the
HTML-file
* which started the applet (i.e. the HTML-file containing the <applet
..../>-tag)!
* Furthermore, the path of the resource is prefixed with the class'
package name.
* Thus, if, say, a class named "a.b.c.SomeClass" is packaged into as file
* "<somedir>/lib/SomeName.jar" and the starting .html-file is in
"<somedir>/html",
* then the style sheet with the above name has to be in
* "<somedir>/html/a/b/c/css/someName.css"!
* Putting it into the .jar at path "a/b/c/css/service.css" (as one would
for a
* "normal" application's .jar file) will only yield null URLs!
* And - even more nasty and confusing: that "normal" location works with
the applet
* viewer but NOT in a real applet (i.e. when started in/from a browser)!
