Output from tools/derbyrunjartest.java can be mixed
---------------------------------------------------
Key: DERBY-1572
URL: http://issues.apache.org/jira/browse/DERBY-1572
Project: Derby
Issue Type: Bug
Components: Regression Test Failure, Test
Affects Versions: 10.2.0.0
Reporter: Knut Anders Hatlen
Priority: Minor
tools/derbyrunjartest.java has occasionally failed in the nightlies, for
instance
http://www.multinet.no/~solberg/public/Apache/DerbyJvm1.4/testlog/Linux-2.6.14-1.1644_FC4_i686-i686/416774-derbyall_diff.txt
and
http://www.multinet.no/~solberg/public/Apache/Derby/testlog/SunOS-5.10_i86pc-i386/416051-derbyall_diff.txt.
The symptom is either that the output is mixed or that parts of it is missing.
This is most likely caused by the writing of output from the forked java
processes happening in separate threads. The runtool() method only waits for
the forked processes to finish, not for the output processing. The problem
would probably go away if BackgroundStreamSaver.finish() were called from
runtool().
