Lua中如何捕获异常？我正在使用LuaJava

我正在使用luajava。当lua执行错误时，我无法捕获异常，然后jdk崩溃了。那么我怎样才能捕获lua中的异常呢？我只是捕获这样的错误（java代码）：

LuaState ls = LuaStateFactory.newLuaState();
ls.openLibs();
String luaPath = "test.lua";
int isCompile = ls.LdoFile(luaPath);
if(isCompile==0){
    log.info(luaPath+" compile success!");
}else{
    log.info(luaPath+" script does not exist or compile failed!");
}

当lua有内部错误时，我无法捕获。那么如何捕获lua中的异常呢？

当lua执行错误时，JVM显示错误，而不是异常。如何捕获 Java 中的错误？

I am using luajava.
When lua execute wrong,I cannot catch exception,and then jdk crashed.
So how can I catch exception in lua?I just catch error like this(java code):

LuaState ls = LuaStateFactory.newLuaState();
ls.openLibs();
String luaPath = "test.lua";
int isCompile = ls.LdoFile(luaPath);
if(isCompile==0){
    log.info(luaPath+" compile success!");
}else{
    log.info(luaPath+" script does not exist or compile failed!");
}

When lua has internal error,I cannot catch.
So how can I catch exception in lua?

When lua executes error, JVM shows an error, not an exception.
How can I catch the error in Java?

有点黑客，但我能想到解决这个问题的唯一方法是做这样的事情：

LuaState ls = LuaStateFactory.newLuaState();
ls.openLibs();
String luaPath = "test.lua";
int isCompile;
try {
    isCompile = ls.LdoFile(luaPath);
} catch (Exception ex {
    ex.printStackTrace(System.err);
    isCompile = 1;
}
if(isCompile==0){
    log.info(luaPath+" compile success!");
}else{
    log.info(luaPath+" script does not exist or compile failed!");
}

抱歉，如果这不是你所要求的，但是 LuaJava 文档毫无价值，所以我不知道是什么具体的运行时异常是。

Bit of a hack, but the only way I can think of to fix this is to do something like this:

LuaState ls = LuaStateFactory.newLuaState();
ls.openLibs();
String luaPath = "test.lua";
int isCompile;
try {
    isCompile = ls.LdoFile(luaPath);
} catch (Exception ex {
    ex.printStackTrace(System.err);
    isCompile = 1;
}
if(isCompile==0){
    log.info(luaPath+" compile success!");
}else{
    log.info(luaPath+" script does not exist or compile failed!");
}

Sorry if this isn't what your asking, but the LuaJava doc is worthless, so I have no idea what the specific runtime exception is.
