JCK : TCK-jnlp 6 b03
J2SE : FAIL - originally found in JDK 6u2 b02, also exists in 6u1
Platform[s] : FAIL - originally found on solaris-sparc
switch/Mode : FAIL - default

TCK-jnlp test api/javax_jnlp/DownloadService/index.html#interactive oftenly hangs on solaris10-sparc platform, i.e. exits with status -2. Problem is not always reproducible.
From my experience test passes more often if harness is run on 6u1. I ran it four times in the configuration harness runs on 6u1 and javaws from 6u2 and it passed three times. If both harness and javaws run 6u2 test almost always hangs but still sometimes passes.
