Hi,

I have a problem with LTW and reweaving...

While debugging if I change the content of a method (ex. the text of a System.out) and save the file, it wouldn't reflected. But if I save the save file again, this time the changes are reflected. And it repeats on cycles of two saves.

The rare is that when I save and the changes are not reflected, in log appears the next two lines and when I save the file and changes are reflected this lines are not showed :

[AppClassLoader@2bbd86] info processing reweavable type test.weaved.Test: test\weaved\Test.java

[AppClassLoader@2bbd86] info successfully verified type test.aspects.TestAspect exists. Originates from test\aspects\TestAspect.java

This lines comes from the method processReweavableStateIfPresent(String, BcelObjectType) on the class org.aspectj.weaver.bcel.BcelWeaver

My environment is:

Windows XP SP3 32 bits

Sun Java 1.6.0 Update 19 JDK

Eclipse 3.5.1

AspectJ 1.6.9 M2 (the same occurs with 1.6.8)

Project: A clean new basis java project that only has this test and AspectJ

If a test project is needed, please let me know (is possible to attach files to mails of this mail list ?)

Next is the console log (lines with #### are my comments of actions realized and expected behavior):
