包冲突是开发过程中很常见的问题：
其表现有：
1.明明在eclipse中能够索引到某个类，运行时却报出找不到类。
2.明明在eclipse中能够索引到某个类的方法，运行时却报出找不到方法。
3.类及方法都有，以正确编译成了.class文件，在本机跑的好好的，发到测试或者正式环境就

Given a string s1, we may represent it as a binary tree by partitioning it to two non-empty substrings recursively.
Below is one possible representation of s1 = "great":
select p.spid,c.object_name,b.session_id,b.oracle_username,b.os_user_name from v$process p,v$session a, v$locked_object b,all_objects c where p.addr=a.paddr and a.process=b.process and c.object_id=b.
