Oleg Ignatenko commented on IGNITE-7716:
----------------------------------------
Relevant excerpt from stack trace from TC log:
{noformat}
[2018-02-15 11:11:13,858][ERROR][main][root] Test failed.
java.awt.AWTError: Toolkit not found: sun.awt.HToolkit"
at java.awt.Toolkit$2.run(Toolkit.java:867)
at java.awt.Toolkit$2.run(Toolkit.java:855)
at java.security.AccessController.doPrivileged(Native Method)
at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:854)
at java.awt.Desktop.isDesktopSupported(Desktop.java:169)
at org.apache.ignite.ml.math.Tracer.isBrowseSupported(Tracer.java:363)
{noformat}
Above suggests that *reason for failure is incorrect configuration of TC host*.
Specifically, the following is required for this test (and all other tests
relying on public Java AWT API) run correctly in environment like one indicated
by above stack trace:
# system properties need to be set as required eg
[here|https://holistictendencies.wordpress.com/2011/10/13/truly-headless-awt-operation-on-macos-x/|"Truly
headless AWT operation ..."]: {noformat}-Djava.awt.headless=true
-Dawt.toolkit=sun.awt.HToolkit{noformat}
# class referred in system property {{awt.toolkit}} (in example above it's
{{sun.awt.HToolkit}}) must be present in JRE (for example on my machine this
class can be found in {{rt.jar\sun\awt}})
[~vveider] - could you please check if involved TC host
([publicagent06_9095|https://ci.ignite.apache.org/agentDetails.html?id=170&agentTypeId=170&realAgentName=publicagent06_9095])
is configured as explained above or maybe something is missing?
