Dear All,
I am having the same problem as Cédric, performing system copy of ECC 6.0 Support Release 3 Netweaver 7.0 withSWPM 1.0 SP08
Tried similar steps, switching Java versions and environment variables etc.
Still with same results, where it hangs at "Install Java Engine" phase.
Couldn't find any solutions yet as of now.
Unable to attached sapinst_dev.log file here though.
Dearly need advise and help on this.
Regards.
Iyadz
