app.jbbres.com Posted October 24, 2010 Share Posted October 24, 2010 Hi there, CCleaner version: v2.36.1233 OS: Windows XP, Vista 7 I would like to report a bug in the Java cache cleaning with CCleaner that has an impact on Java installation. CCleaner deletes the content of the Java cache, but it delete too much (or not enought, that's up to your designers to decide ). The impact is that Java Web Start applications installed on the computer will not run properly after a cleaning. However application shortcuts are still available. When double-clicking on them, Java Web Start will display an error message "Unable to launch the application". To reproduce the bug: Install a Java Web Start application (for example http://app.jbbres.com/actions) Notice the application shortcut on the desktop. When double-clicking, the application run properly. Run a cleaner with CCleaner. Make sure to select "Sun Java" in the "Applications" tab. Re-try to launch run the Java Web Start application from the desktop. The application is not running anymore. The user needs to re-install the application from the editor web site in order to fix the issue As I was saying, it is up to you to decide if CCleaner should be deleting the desktop and start menu shortcuts, or not deleting the required files to perform properly (I'm more inclined to go for the second solution, mainly because like that my users will stop asking me why there is problem with the application after they run CCleaner ). Anyway, keep on the good job. // JB app.jbbres.com Link to comment Share on other sites More sharing options...
temp1234 Posted October 28, 2010 Share Posted October 28, 2010 Yeah this happens to me to, it's quite annoying. BTW It also breaks uninstall of Java web start apps from the add/remove dialog. Link to comment Share on other sites More sharing options...
Moderators Nergal Posted October 28, 2010 Moderators Share Posted October 28, 2010 You need to find where the java program installs (it's one of the folders labeled in numeric order) and add it to the exclude option of ccleaner. The best way to do this is clean Java in ccleaner, sign on the the java app (i.e. redownload it, don't go to anyother java things) then find the settings file(s) and exclude them in CCleaner options. i.e. to keep my daytrotter downloader information I exclude C:\Users\XXXX\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\21\63d9cc55*.* C:\Users\XXXX\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\31\1e58a71f*.* C:\Users\XXXX\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\55\4e9f2df7*.* C:\Users\XXXX\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\muffin\5ad1384d*.* Alternately don't use ccleaner to clean java ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF. Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark) ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.
