garbage collection take too much time to execute....

[- -]

I agree that 3.4.5 is old but it is the "current release" of mingw,
also cygwin is using 3.4.5 is its "stable" releases....
As said before I'm not familiary with gcj and mingw and I'd like to
use for now (at least to understand the limitation and boundary of gcj and swt) stable or official releases.

May I ask if someone could compile and run my simple snippet in order to see if in the latest release is present the same problem?
This is the command to compile:

gcj --classpath="org.eclipse.swt.win32.win32.x86_3.3.3.v3349.jar" -I. -c -o snippet.o snippet.java

and after:

gcj -o  snippet.exe  --static -mwindows --main=snippet ./snippet.o -L. -lswt


I'm  trying to donwload the alfa release of mingw it contains gcj release 4.3.0 may be tomorrow I'll success to compile...


Thanks you a lot for any support and hits..
