Comment 1 Svata Dedic 2001-04-06 18:32:55 UTC 
Hmm, it seems that nobody counted for this. If you clear fs capability to 
support compilation, you should not be able to start the compile process first 
of all :-)
Comment 2 Svata Dedic 2001-04-07 12:35:41 UTC 
Raising priority.
During investigation of this bug I found out that the compiler can - under some 
circumstances - generate .class files to different filesystem although it was 
not configured to. The code that selects the target location makes guesses in 
some situations and those guesses may be incorrect.
Comment 3 Svata Dedic 2001-04-12 17:03:08 UTC 
Fixed in dev trunk, pending merge for 3.2
Comment 4 Svata Dedic 2001-04-17 18:47:41 UTC 
*** Issue 11488 has been marked as a duplicate of this issue. ***
Comment 5 Svata Dedic 2001-04-18 15:45:36 UTC 
merging
Comment 6 Svata Dedic 2001-04-18 15:59:31 UTC 
Merged to 3.2
Comment 7 Quality Engineering 2003-07-01 13:15:07 UTC 
Resolved for 3.4.x or earlier, no new info since then -> closing.
