ORA-29516: Aurora assertion failure: Assertion failure at eox.c:332
Uncaught exception System error: java/lang/UnsupportedClessVersionError
as the error says your class version is not recognized by Oracle.
- check your JAVA version by invoking:
- check which JAVA version is used by Oracle 11g by invoking:
[($ORACLE_HOME/jdk/bin/)|( %ORACLE_HOME%\jdk\bin)]java -version
probably the two versions are not the same.
Solution use the same version for compiling *.java files, or if you want to be 100% sure use
