Jesse Glick commented on SUREFIRE-1226:
---------------------------------------

[~tibor17] I agree with [~jloc...@redhat.com]’s expectation. Was unpleasantly 
surprised to update to 2.19.1 (so as to pick up SUREFIRE-1138) and finding test 
output like

{code:none}
java.lang.NullPointerException
        at 
jenkins.plugins.git.AbstractGitSCMSourceTest.fileAt(AbstractGitSCMSourceTest.java:89)
        at 
jenkins.plugins.git.AbstractGitSCMSourceTest.retrieveRevision(AbstractGitSCMSourceTest.java:76)
{code}

(nonsensical since line 89 of the test could not possibly throw this 
exception!) where before I had gotten

{code:none}
java.lang.NullPointerException
        at 
jenkins.plugins.git.AbstractGitSCMSource.resolveGitTool(AbstractGitSCMSource.java:157)
        at 
jenkins.plugins.git.AbstractGitSCMSource.retrieve(AbstractGitSCMSource.java:269)
        at jenkins.scm.api.SCMSource.retrieve(SCMSource.java:295)
        at 
jenkins.plugins.git.AbstractGitSCMSource.retrieve(AbstractGitSCMSource.java:358)
        at jenkins.scm.api.SCMSource.fetch(SCMSource.java:277)
        at 
jenkins.plugins.git.AbstractGitSCMSourceTest.fileAt(AbstractGitSCMSourceTest.java:89)
        at 
jenkins.plugins.git.AbstractGitSCMSourceTest.retrieveRevision(AbstractGitSCMSourceTest.java:76)
{code}

which clearly indicates the problem.

If you are going to trim stack frames inside the test (which I do not advise), 
you need to leave *some* clue to users, so they do not have to spend an hour 
bisecting and searching bug trackers! For example

{code:none}
java.lang.NullPointerException
        …5 stack frames elided, set trimStackTrace=false to display
        at 
jenkins.plugins.git.AbstractGitSCMSourceTest.fileAt(AbstractGitSCMSourceTest.java:89)
        at 
jenkins.plugins.git.AbstractGitSCMSourceTest.retrieveRevision(AbstractGitSCMSourceTest.java:76)
{code}

> even more trimmed.
