Neither the build nor jstack can be stopped by Ctrl-C and I have to kill native2ascii again. --Max On Feb 8, 2014, at 15:44, Alan Bateman <alan.bate...@oracle.com> wrote: > On 08/02/2014 06:54, Wang Weijun wrote: >> : >> >> The command (according to ps -f) is >> >> /java/re/jdk/1.6.0/archive/fcs/binaries/linux-amd64/bin/native2ascii >> -J-XX:-PrintVMOptions -J-XX:+UnlockDiagnosticVMOptions -J-XX:-LogVMOutput >> -J-Xmx512m -J-Xms512m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -reverse >> -encoding UTF-8 >> > This looks like the original (Sun) JDK 6 from 2006 and so pre-dates OpenJDK. > I think I'd start with jstack to see if I can get a thread dump, this might > give you a hint as to what it is doing. > > -Alan.
