New Revision: 217
Modified:
branches/federation/dna-spi/src/test/java/org/jboss/dna/spi/graph/connection/RepositoryConnectionPoolTest.java
Log:
Attempt #3 to fix a test that runs locally but fails on Hudson. These load tests run several clients simultaneously, and it looks like the jobs don't finish in the allotted time on the Hudson boxes, while they do locally. This change ramps up the allotted time and reduces the number of concurrent clients (to something that is still representative and that still accomplishes the goal of the test). Hopefully these will work.
