The git client 1.19.6 has been running since 3/22/2016 on the master
without errors, so it seems the feature to detect the jdk works as desired,
at least when run on the master. The class version issue only shows up
when we configure the job to run on a slave, It is also interesting that
the problem only shows up on the first execution on the slave. I got the
error two ways:
1. deleted all jar files in .jenkins/cache/jars, then disabled and
relaunched the slave. then kicked off a build. The first build got the
class version error.
2. modified an existing job to build on a different slave, one it had not
built on before. Again, the first build got the class version error.
For both cases, once the build had been attempted once, subsequent builds
get the NoClassDefFoundError.
Caused by: java.lang.NoClassDefFoundError: Could not initialize class

org.eclipse.jgit.lib.BaseRepositoryBuilder.setupWorkTree(BaseRepositoryBuilder.java:620)
at
org.eclipse.jgit.lib.BaseRepositoryBuilder.setup(BaseRepositoryBuilder.java:556)
at org.eclipse.jgit.sto
This leads me to think that for the first build, something is running on master
that does not run for subsequent builds once the workspace has been created on
the slave. Just throwing that out since I have no other explanation for the
class version errors.
