[aspectj-users] method <clinit>code size too big problem when weaving

[司徒诚颢 <situchenghao@xxxxxxxxxxxx>]

Hi,

 

When my aspectj is weaving to a class which has 3200 advises, eclipse reporting Error "problem generating method packageXX.ClassXX.<clinit> : Code size too big: 78716".

I know this is caused by the limitation of the length of java method can not longer than 64kb.

I modify this class and reduce the number of advises to only 3 and recompile it, and find it will generate a static initial method like below:

static
    {
        Factory factory = new Factory("StubClass.java", Class.forName("StubClass"));
        ajc$tjp_0 = factory.makeSJP("method-call", factory.makeMethodSig("1", "get", "pachageX.ClassX", "java.lang.String:", "string:", "", "java.lang.String"), 13);
        ajc$tjp_1 = factory.makeSJP("method-call", factory.makeMethodSig("1", "get", "pachageX.ClassX", "java.lang.String:", "string:", "", "java.lang.String"), 15);
        ajc$tjp_2 = factory.makeSJP("method-call", factory.makeMethodSig("1", "get", "pachageX.ClassX", "java.lang.String:", "string:", "", "java.lang.String"), 18);
    } 

That means if there are 3200 advises, there will be 3200 statements in the static initial method, which may cause the error.

And below is my around method:

Object around(String var)  : aroundGet(var)
 {
  //proceed(value);
  String key = var;
  int line = thisJoinPoint.getSourceLocation().getLine();
  Object value = findProperties(line, key);  
  return value;
 } 
 private Object findProperties(int line, String key)
 {
  Object result = null;
  TestData testData = BaseTestCase.getTestData();
  result = testData.getValue(line, key);
  return result;
 }

 

And another thing is I find that the logic in the around() method will determine the weaved code, if I just return a random number in the around(), Aspectj will not generate static initial method, under this scenario, the weaving can success is there are 3200 advises.If I change the around() to :

Object around(String var)  : aroundGet(var)
 {
  return new java.util.Random().nextInt(10000);
 }

It will generate code like below:

private static final String get_aroundBody4(StubClass stubclass, SomeClass someclass, String s)
    {
        return someclass.get(s);
    }

    private static final Object get_aroundBody5$advice(AroundGetMethods this, String var, AroundClosure ajc_aroundClosure, AroundGetMethods aroundgetmethods, String s, AroundClosure aroundclosure)
    {
        return Integer.valueOf((new Random()).nextInt(10000));
    }

 

By the way, when I use LTW to weaving this class, aspects generating OutOfMemoryError.

But I think if the problem of static way is solved, the LTW should be OK too.

 

So how could I solve this problem? Is there some good suggestions?

Thanks for the help.
