NullPointerExceptions on ColdFusion 8 0 1

Hi @all, I use a cold fusion 8.0.1 server on a windows 2003 server (x64 edition of both products). The application use a ms sql 2005 database, I use the current sql jdbc driver from microsoft for sql 2005. Some times, some days we get null pointer exceptions at different code lines / templates. -- snip -- java.lang.NullPointerException at coldfusion.sql.QueryDetails.equals(QueryDetails.java:112) at coldfusion.util.LruCache.removeEntry(LruCache.java:104) at coldfusion.util.LruCache.reap(LruCache.java:212) at coldfusion.util.LruCache.get(LruCache.java:190) at coldfusion.sql.Executive.getCachedQuery(Executive.java:1309) at coldfusion.tagext.sql.QueryTag.setupCachedQuery(QueryTag.java:708) at coldfusion.tagext.sql.QueryTag.doEndTag(QueryTag.java:517) at ... -- snip -- All NPEs occur when using cached querys (they occur on different cfquery-tags). The first lines of the stack trace are always the same. I've updated the ms sql jdbc driver for a few weeks ago. In the past the above NPEs occured, too. Is my NPE problem a jdbc driver related issue or a cold fusion issue? Can anybody give me some hints? Have anybody any ideas? Regards, Karl-Heinz

From that stack trace, it sure looks like a bug in the query cache. You filed it with Adobe? ----- Excess quoted text cut - see Original Post for more -----
