I downloaded http://www.zentus.com/sqlitejdbc/dist/sqlitejdbc-v044-nested.tgz In that file is sqlitejdbc-v044-nested.jar. Trying to analyze that file using the FindBugs 1.3.3 GUI ultimately results in hang.
The analysis goes on for a while (CPU stays at 100% for a while). However, after a period of time the analysis apparently stops (CPU drops to just a few %), but the GUI is unchanged.

Just noticed that with 1.3.3 the last copyright year in the about box is 2007. It should be 2008.

Here's the code:

// Unhash
final int hashPos = fp.fieldInfo.name.hashCode() & fieldDataHashMask;
FieldData last = null;
FieldData fp0 = fieldDataHash[hashPos];
while(fp0 != fp) {
last =...

Ran FindBugs against Apache Lucene 2.3.1. Was looking at the results and in several cases it gives "Computation of average could overflow" warnings. The text description talks about right shifts to do division. The problem is that the lines that are highlighted do not have right shifts in them. However, line immediately before it does. For some reason, the line number highlight seems to be...

Warning". So, some post-processing is trying to make sure that the text is proper HTML and is screwing...
