The command bean is instantiated and a try catch block is used to catch exceptions generated from a duplicate user, an invalid credit card, or an unauthorized credit card.
命令bean被实例化，trycatch块被用于捕捉由于重复的用户、无效的信用卡或未经认证的信用卡而产生的异常。
This is not a debugger bug, but it is known issue with try catch block debug information. See the following disassembled code for an example of a try catch block in the debugger.
这并不是调试器的bug，但是这是针对trycatch块调试信息的一支问题。
It iterates the list of catch blocks, and if it finds one that catches Exception, it looks again for a catch block that catches RuntimeException for the same range of bytecodes.
它将迭代捕获块的列表，如果发现捕获Exception的块，它会再次查找捕获块，该捕获块将捕获字节码同一范围的RuntimeException。
To detect this bug pattern, you'll need to know where the try-catch blocks are, what might be thrown out of the try block, and what is caught in the catch blocks.
要检测此bug模式，则需要知道try -catch块的位置、try块可能抛出的内容以及在catch块中将捕获的内容。
If the stored procedure contains a TRY... CATCH construct, the error transfers control to the CATCH block in the stored procedure.
如果存储过程包含TRY…CATCH构造，则错误会将控制传输给存储过程中的CATCH块。
If the stored procedure contains a TRY... CATCH construct, the error transfers control to the CATCH block in the stored procedure.
如果存储过程包含TRY…CATCH构造，则错误会将控制传输给存储过程中的CATCH块。
