Unsupported major.minor version 52.0 error post upgrade
Issue:
After 11.0 (from 8.1 to 11..0) successful upgrade, application does not start due to renaming of JRE folder not happening automatically.
Exception in thread "main" java.lang.
UnsupportedClassVersionError
: com/adventnet/servicedesk/server/utils/SDResourceCheck : Unsupported major.minor version 52.0
at java.lang.ClassLoader.defineClass1(Native Method)
Fix:
Manually rename the JRE to JRE_OLD and JRE_NEW to JRE.
Start the application now and check, it should work.
