Hi,

When I export my eclipse application and place it in a read-only folder
it fails with the following causing exception:

Caused by: java.lang.ClassNotFoundException:
org.caleydo.core.data.perspective.table.TablePerspective
at
org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:513)
at
org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:429)
at
org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:417)
at
org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass(DefaultClassLoader.java:107)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
... 91 more

According to this help page [1] starting without reading permissions
should work.

I've just refactored the Class TablePerspective that seems to be the
cause of this, however, I don't see why it should work with rw but not
with r permissions. The package containing the class is correctly exported.

This is very annoying since I can't deploy the application using linux
packages or windows installers which place it in read-only directories.

I appreciate any help. Thanks!

The solution was to delete the cache in my users's local .eclipse
folder. It seems to have contained content from before the refactoring
and wasn't updated. Simply removing the .eclipse folder did the trick.
