Error: Could not find or load main class <PATH TO JDK MENTIONED BELOW>

While executing command

java <path_to_jdk> -jar <path_to_opatch_generic.jar> -silent oracle_home=<path_to_oracle_home>

I'm applying Patch 28186730: OPATCH 13.9.4.2.4 FOR FMW/WLS 12.2.1.3.0, 12.2.1.4.0 AND 14.1.1.0.0

- Tried setting JAVA_HOME & ORACLE_HOME as well but issue persists.

- Currently on Linux env. & recently upgraded the env. from 12.2.1.3 to 12.2.1.4 following Doc ID 2309958.1
