Changed paths:
M src/main/java/com/cloudbees/jenkins/support/impl/ThreadDumps.java
Log Message:
-----------
#2 (CPU) and #3 (deadlocks) did not consider the fact that JMX calls can
throw UOE.
In certain cases (observed “in the wild”) this led to some slaves having an
empty thread dump;
errors.txt listed the problem:
Could not attach 'nodes/slave/…/thread-dump.txt' to support bundle
