Tried and it didn't help. The following was obtained during jdk build:

kernel: UFS_GJGC: Cannot delete /var/.deleted/#1202150:230144382 (error=2)
[some seconds later]
$ find /var/ -inum 1202150
/var/tmp/tmp/hsperfdata_root/72795
kernel: UFS_GJGC: Cannot delete /var/.deleted/#1202150:230145003 (error=2)
[some seconds later]
$ find /var/ -inum 1202150
/var/tmp/tmp/hsperfdata_root/81211
^^^^^^^^^^^^ - btw, my /tmp is symlink to /var/tmp/tmp

So, even adding generation count doesn't fix the issue. Thus it seems
that there seems to be some other kind of race condition in 6.x gjournal
code.
