Hello,

I have this issue when I try to run ./sqlcl/bin/sql:

Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

My settings are:

SQLcl	18.4.0.007.1818
JAVA_HOME	/usr/java/jdk1.8.0_131/jre
ORACLE_HOME	/opt/oracle/product/11.2.0.4/db_1
OS	CENTOS 7

This is happening because SQLcl is finding and using a lower version of Java than you indicate in your post, probably because sql script gives precedence to the JRE found in the ORACLE_HOME, as discussed in
