UCS Manager launch error

I've been fighting with JAVA on my PC for a few days. Trying to launch the Cisco UCS manager - JAVA based. Would kick up the error :


JARSigningException: Found unsigned entry in resource: http://{HOST}.{DOMAIN}/ucsm/unpacked/OfficeLnFs_2.7.jar


Nothing on google. Removed the vast collection of JRE versions, reinstalled, blaah blaah blaah. Still fails. Threw my toys out, stomped away in a huff complaining about JAVA failing to live up to its expectations due to inept programmers ..


Then I twigged. I'd been debugging one of our bespoke JAVA apps last week and had disabled the 'Keep temporary files on my computer' JRE setting.


Corrected, problem fixed .. huff gone.
