jdbc batch insert失败但是没有异常怎么排查

public void executeBatch(Connection connection) throws SQLException {
long start = System.currentTimeMillis();
if (rows.size() != 0) {
try {
rows.forEach(row -> {
try {
JDBCUtils.setRecordToStatement(this.statement, this.fieldTypes, (Row) row);
this.statement.addBatch();
} catch (SQLException e) {
throw new RuntimeException(e);
}
});
int[] ints = this.statement.executeBatch();
connection.commit();
int j = ints.length;
if (rows.size() != j) {
throw new RuntimeException(String.format(“入库数量不一致, Rows.size():%d, 执行成功条数，批量执行返回int数组长度：%s”, rows.size(), j));
}
long s = System.currentTimeMillis() - start;
LOG.info(“批量入库{}条数据，用时{}ms, 实际入库{}条数据”, rows.size(), s, j);
rows.clear();
} catch (Exception e) {
LOG.info(“批量入库失败，转为单条入库…{}, rows:{}”, e, rows);
connection.rollback();
connection.commit();
this.statement.clearBatch();
executeUpdate(connection);
}
}
}

public synchronized void executeUpdate(Connection connection) {
    long start = System.currentTimeMillis();
    AtomicInteger success = new AtomicInteger();
