Getting a Hikari Pool Initialization error

Getting this on startup in my JRE 11. No-one else in the team seems to get it. It does resolve if I compile and run in JDK 8.

HikariPool-1 - Exception during pool initialization

java.nio.BufferOverflowException: null
    at java.base/java.nio.HeapByteBuffer.put(HeapByteBuffer.java:221)
    at java.base/java.nio.ByteBuffer.put(ByteBuffer.java:978)
    at oracle.net.ano.AnoCommNIO.d(Unknown Source

etc

I had the same issue but with Java 8 as well as Java 11. I tried passing this VM argument and it worked for me:

-Doracle.jdbc.javaNetNio=false

Or, we can also set it as properties if creating an OracleDataSource:

OracleDataSource oracleDataSource = new OracleDataSource();
oracleDataSource.setURL(jdbcUrl);
oracleDataSource.setDriverType(dbDriver);
Properties properties = new Properties();
//... other properties if needed
properties.setProperty("oracle.jdbc.javaNetNio", "false");
    
oracleDataSource.setConnectionProperties(properties);

Or if creating a HikariDataSource, we can use it as:

HikariConfig poolConfig = new HikariConfig();
poolConfig.setJdbcUrl(jdbcUrl);
poolConfig.setDriverClassName(jdbcDriver);  
//...  other properties if needed
poolConfig.addDataSourceProperty("oracle.jdbc.javaNetNio", "false");
