## Bug Report **For English only**, other languages will not accept. Before report a bug, make sure you have: - Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues). - Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview). Please pay attention on issues you submitted, because we maybe need more details. If no response anymore and we cannot reproduce it on current information, we will **close it**. Please answer these questions before submitting your issue. Thanks! ### Which version of ShardingSphere did you use? 5.0.0-beta ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? ShardingSphere-JDBC ### Expected behavior Lock wait timeout exceeded; try restarting transaction ### Actual behavior ```java java.lang.IndexOutOfBoundsException: Index: 3, Size: 3 at java.util.LinkedList.checkElementIndex(LinkedList.java:555) at java.util.LinkedList.get(LinkedList.java:476) at org.apache.shardingsphere.driver.executor.batch.BatchPreparedStatementExecutor.accumulate(BatchPreparedStatementExecutor.java:163) at org.apache.shardingsphere.driver.executor.batch.BatchPreparedStatementExecutor.executeBatch(BatchPreparedStatementExecutor.java:143) at org.apache.shardingsphere.driver.jdbc.core.statement.ShardingSpherePreparedStatement.executeBatch(ShardingSpherePreparedStatement.java:548) ``` ### Reason analyze (If you can) - not use transaction, code will execute this method org.apache.shardingsphere.infra.executor.kernel.ExecutorEngine#parallelExecute ，code is ： ```java private <I, O> List<O> parallelExecute(final Iterator<ExecutionGroup<I>> executionGroups, final ExecutorCallback<I, O> firstCallback, final ExecutorCallback<I, O> callback) throws SQLException { ExecutionGroup<I> firstInputs = executionGroups.next(); **//the other group is async execute ** Collection<ListenableFuture<Collection<O>>> restResultFutures = asyncExecute(executionGroups, callback); **// the first group will sync execute ，this the question ** return getGroupResults(syncExecute(firstInputs, null == firstCallback ? callback : firstCallback), restResultFutures); } ``` **in above code ,if the first group thrown expection，i can get ，it is my hope；but if the first group execute right，but the other group throw exeption，i can not get； Whether an exception is thrown，we see the following code** - Whether synchronous or asynchronous ，all will execute this method In the end ```java org.apache.shardingsphere.infra.executor.sql.execute.engine.driver.jdbc.JDBCExecutorCallback#execute(org.apache.shardingsphere.infra.executor.sql.execute.engine.driver.jdbc.JDBCExecutionUnit, boolean, java.util.Map<java.lang.String,java.lang.Object>) private T execute(final JDBCExecutionUnit jdbcExecutionUnit, final boolean isTrunkThread, final Map<String, Object> dataMap) throws SQLException { .... try { ..... return result; } catch (final SQLException ex) { //**when sync execute ,isTrunkThread=true,will execute next code ,and throw exception；but async execute ,isTrunkThread=false,will return null ** if (!isTrunkThread) { return null; } Optional<T> saneResult = getSaneResult(sqlStatement); if (saneResult.isPresent()) { return saneResult.get(); } sqlExecutionHook.finishFailure(ex); SQLExecutorExceptionHandler.handleException(ex); } } ``` ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. ```java try { connection = dataSource.getConnection(); preparedStatement = connection.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS); for (int index = 0; index <itemIds.size(); index++){ if(index==0){ // the lock row belong to first group or the other group will make a difference connectionLock = lockOneRowData(itemIds.get(index)); } itemCollects.get(index).setAppId(replaceAppId); setParametersTopreparedStatement(preparedStatement, itemCollects.get(index)); preparedStatement.addBatch(); } replaceCount=preparedStatement.executeBatch(); } catch (SQLException e) { e.printStackTrace(); exception =e; }finally { Common.rollback(connectionLock); } Assert.assertTrue(getExceptionMsg(exception).toString().contains("Lock wait timeout exceeded; try restarting transaction")); ``` ### Example codes for reproduce this issue (such as a github link). -- This is an automated message from the Apache Git Service.
