Description:
|
After upgrading the Apache httpClient to 4.4, I found that other plugins such as Git-Client/Maven-plugin that also uses httpClient with different versions collapses with ours. So After I added the Mask-Classes attribute the problem was gone, but it looks like this isolated environment dose not apply for Slaves.
I found out
the
that
in the *RemoteClassLoader* while it tries to find a specific class URL, *Which.classFileUrl(class)* uses the getResource method. This method is not override by the *hudson.util.MaskingClassLoader*. So the class comes from the right source under the plugin itself, but the resource URL of the same class can came from +other+ source such as other plugins that contain the same classes.
Error example that I get:
at hudson.model.Executor.run(Executor.java:240)
