gcj (GCC) 4.2.0 20060726 (experimental)
Deserialize an object fails on Class.forName(). I assumed this would work
because class.forName() doesn't use the stack unwinder any longer.
Exception:
Exception in thread "main" java.lang.ClassNotFoundException: Serialisation

Before a change in the SJLJ exception routines for Windows, Serialization was broken because _Jv_StackTrace::GetCallingClass() always returned NULL instead of the jclass. 2. After that change, _Jv_StackTrace::GetCallingClass() was implemented but it actually returns the wrong jclass, what leaves Serialization broken. Because the mentioned SJLJ exception introduced a regression in JNI handling which affects some of my programs (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29477), I work with a GCJ without that patch. So the attached patch to get Serialization to work only works by reverting the mentioned SJLJ change. It's really time to get DWARF excptions running for mingw. It really would be the most prober solution... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28531 ^ permalink raw reply [flat|nested] 6+ messages in thread
