Subject [jira] [Commented] (LUCENE-2988) trunk 'ant test' hangs
Date Thu, 24 Mar 2011 16:38:06 GMT


Doron Cohen commented on LUCENE-2988:

Thanks Robert for looking into this!

bq. it seems they are from the 'ant' jvm, not the forked process that actually runs the tests

Indeed, now I notice that too... when 'ant test' hanged I used <CTRL BREAK> to get the
thread dump and did not realize the ant JVM stands in between... That console is lost and
I don't know the exact location in the tests when that happened - too bad. 

bq. It could be the case here that its just in some ultra-slow test such as TestIndexWriterOnDiskFull...
this one frequently takes several minutes for me even on Sun JRE.

I was away for half an hour so its something slower...

I was not able to reproduce this, and also in the meantime found out that I was using incompatible
ant version - 1.8.1. 

So thinking of closing this for now, will reopen it if it will reappear with ant 1.7.1.

> Running 'ant test' from trunk on XP in a Cygwin shell hangs.
> There was no progress in the console for a long time, so i stopped the program.
> Before stopping it, created 5 consecutive thread dumps to see where the code is.
> It is not clear what is going on - does not seem like a Lucene code I think but not sure.
> Opening this issue to keep an eye on this - I will try with other JDKs to see if this
is persistent.
> Also, when first seeing this had local changes of two issue: LUCENE-2986 and LUCENE-2977
- I think the changes in these issues are related but will repeat the tests without these
