更改会话挂起或导致ORA-01013

如何解决更改会话挂起或导致ORA-01013

我有以下代码块，并且在执行ALTER SESSION语句时，它挂起或抛出ORA-01013，这取决于我们是连接到Oracle 12r2还是19.3，以及哪个版本的OJDBC8驱动程序正在被使用：

try(Connection connection = jdbcConnection.connect(false)) {
  // We Now have a java.sql.Connection open to the database at this point
  try(PreparedStatement ps = connection.prepareStatement(someQuery)) {
    // We not have a prepared statement based on query,the query is irrelevent
    try (Statement s = connection.createStatement()) {
      // The following statement fails with the ORA-01013 error
      s.execute("ALTER SESSION SET CONTAINER=" + pdbname);
    }
  }
}

如果我将此代码块重做以下内容，问题将消失。

try(Connection connection = jdbcConnection.connect(false)) {
  // We Now have a java.sql.Connection open to the database at this point
  try (Statement s = connection.createStatement()) {
    s.execute("ALTER SESSION SET CONTAINER=" + pdbname);
  }
  try(PreparedStatement ps = connection.prepareStatement(someQuery)) {
    // We not have a prepared statement based on query,the query is irrelevent
  }
  // or put the alter session here
}

根据我的判断，使用Oracle OJDBC8 12.2.0.1会抛出hang或ORA-01013异常；但是，当我迁移到19.x.0.0时，这就是发生此问题的地方。

这是JDBC驱动程序中的错误吗，还是代码编写方式上确实存在问题，即12.2.0.1驱动程序比以后的版本更宽容？
