Doesn't reCrash handle non-argument methods?

[Qingzhou]

Dear sir:

I have downloaded and tried reCrash and its source code, it's really
impressive. But I am wondering why it doesn't handle non-argument
methods(See Transformer.java), why not just preseving "this" object?
Is it said that non-argument methods is easy to crash again so no need
to instrument?

Thanks a lot.

Hi Qingzhou,

We assume that methods with no arguments are less likely to crash.
However, as you pointed out, it is possible to preserve only the
receiver (this) for non-argument methods.

Thanks for your comments.

Thanks.

A new problem, when I was using reCrash to instrument some of my own
classes, I encounted this:

com.thoughtworks.xstream.converters.ConversionException: Could not
call java.security.CodeSource.readObject()
---- Debugging information ----
message : Could not call
java.security.CodeSource.readObject()

I have noticed you have already asked this question to xstream
developer before, do you have any conclusions?
If my version of reCrash or xstream is too old? Seems like an
exception is thrown in xstream library.

Thanks again!

I have geot the cause. Xstream doesn't support thread serialization up
now:(
