Reto Bachmann-Gmür commented on CLEREZZA-320:
---------------------------------------------
Whenever I don't recreate the ClassLoader on every execution
I get the following error:
java.lang.ClassNotFoundException: sun.reflect.MethodAccessorImpl

The puzzling thing is that if I create a new
AbstractFileClassLoader(virtualDirectory, this.getClass.getClassLoader()) it
doesn't try to access this class and works.

> Key: CLEREZZA-320
> URL: https://issues.apache.org/jira/browse/CLEREZZA-320
> Project: Clerezza
> Issue Type: Bug
> Environment: in netbeans, during cpu profiling exclude all java core
> classes
> Reporter: Tsuyoshi Ito
> Priority: Blocker
> Attachments: org.clerezza.test.render.zip, page_reuest_wo_javacore.png
>
>
> during profiling session we detected that rendering ssp is very slow. A lot
> of time is used to execute
> scala.tool.nsc.interpreter.AbstractFileClassLoader.findClass. Seems that each
> execution the classes are (re)loaded. IMO this should not be the case.
