On 3/26/2012, build 1305705 on trunk the IBM 1.7 Windows started failing with
either a hang or
20 failures 190 errors most of which seem to be starting or related to this
error:
Java exception: 'sun.misc.Unsafe incompatible with
java.util.concurrent.ConcurrentHashMap$HashEntry: java.lang.ClassCastException'.
The detail didn't make it to the apache pushout at:
http://people.apache.org/~myrnavl/derby_test_results/main/windows/testSummary-1305705.html
I will attach the output from the failure case.
There were 190 errors:
