Opening a large incorrect Java file freeze UI for 22 secs How to reproduce: 1.) Create copy of a medium sized Java file 2.) In this new file repeat at least 5 times: press Ctrl+A, Ctrl+C, Ctrl+V,Ctrl+V,Ctrl+V 3.) Once you have around 100 000 lines save,you may see the freeze from Bug 550737 4.) Open editor 5.) Open editor -> Freeze Stack trace: Stack Trace at java.base@12.0.1/java.util.HashMap$TreeNode.find(HashMap.java:1911) at java.base@12.0.1/java.util.HashMap$TreeNode.find(HashMap.java:1921) at

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
