Unsupported major.minor version 52.0 error post upgrade


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.

Manually rename the JRE to JRE_OLD and JRE_NEW to JRE.

Start the application now and check, it should work.
