发帖数: 737 | 2 sun jvm 主要用c++写的
ibm production jvm 也是用c++写的，只有jikes rvm是用java写的
intel 和 microsoft的优化编译器也是用c++写的
visual studio大部分都是c++
linux和其他一推用c写的库里面用函数指针来实现c++里的late binding |

Oh yeah, IBM is not only rubbish but also mind controlling, because evidently
everybody else who uses jikes and dares to write statements as complicated as
"if (!foo())" all got screwed up big time by this rubbish JVM, and yet they
just stayed silent all the time.

I think I missed your point in the OP. What exactly is the known bug? Are
you saying jikes has side effects in their file reading methods? |

发帖数: 214 | 6 说说你看到的是什么。ExecuteJava怎么会是直接调用jasper的compiler来编译呢？逻辑
上Ant代码怎么知道该用Jasper,javac还是jike或别的去编译呢？代码里当然是从环境里
找合适的编译工具，reflect动态调用了。Jasper的错误都在TraceStack里看到了，还有
啥可怀疑的呢？
这事儿很简单，错误摆在你面前，想要的方法没找到。就一点，processFile想要得Strin
g[] 参数是个String。你就冲这个问题上啊。无非就是过去JspC类里processFile是接受
的参数，现在不接受了。除了寻找互相兼容的ant和jasper版本，你根本不用在任何其他
方面尝试。
这个错误没有任何玄妙之处啊。org.apache.tools.ant.taskdefs.ExecuteJava.execute(
ExecuteJava.java:172)在调用不存在的org.apache.jasper.JspC.processFile(String[]
。

It depends. For example, for some JVM implementation, it is 4 bytes.
It depends. For some JVM implementation, it is a pointer/reference pointing
to class type structure.
For q2 and q3, the best source is to refer to Sun JDK's source codes or IBM'
s Jikes RVM's source codes. |

找那个十几个google的人没什么用。Search从头做起困难的不仅仅是crawling, index,
serving, ranking这些pipeline,还有下面的infastructure.因为relevance差点可以
忍，特别是可以上一些人力美化一下head query.这样从头做起的，GFS, big table，
cluster的management，自己开发，没有个3-5年别想了。加上用户少，querylog/click
都不行，又没有365那样的本钱用浏览器拿信息，没什么指望的。
现在的search engine很多投资在entity上，这个JIKE离百度还差得很远。用了一下感
觉google 2004年的水平。 |

基本上，编译器都是本身那个语言，至于虚拟机，那个其实是操作系统的一部分。
The Sun JVM is written in C, the original IBM JVM was written in Smalltalk
the HotSpot JVM is written in C++
Someone in fact write a JVM with Java already, Jikes |
