Description Patrick Chuong

When I switch to a new perspective that isn't a java perspective, I get this error: Referenced part does not exist yet: org.eclipse.jdt.ui.PackageExplorer.

Here is the callstack that trigger this error:

I cannot reproduce this. Can you please
1. provide the build ID (is it 3.7 or 3.8?)
2. steps to reproduce
3. entire .log

1. I am using 3.7 for C/C++ Developer.
2. I simply switch perspective to resource perspective (or my custom perspective).
3. The log contains one error status without any stack, the message is "Referenced part does not exist yet: org.eclipse.jdt.ui.PackageExplorer."

I am on vacation this week, if you can't reproduce it, then I'll try to reproduce it next week when I return to the office.

This is a bug in EGit: they place their org.eclipse.egit.ui.RepositoriesView relative to the Package Explorer which of course is not available in the C++ package.

EGit should not reference any JDT stuff in their plugin.xml.

This issue also appears with the scala perspective.
I got this error message when I switch from java to scala perspective.

Either the scala ide has placed one view relative to the package explorer, like Dani Megert said in relation to egit or it is another issue.
