Eclipse is getting very slow when using ctrl+click method name or "Open Type" during debugging after turning on "Show debug values inline"

This is more FYI, but I thought I should mention it.

When I am debugging and I want to open a type via "Open Type" or I want to see a method by ctrl-clicking the method name then Eclipse becomes very slow, and it also does not recover even after debugging has stopped.

I had a look with VisualVM and I noticed

This reminded me that I (for whatever reason) activated "Show debug values inline":

but I quickly forgot about that.

=> Feel free to close this issue, this is more a hint that this experimental feature might cause performance problems for Java.
