Concurrent Modification Exception #6

Open ron-wolf opened 3 years ago

ron-wolf commented 3 years ago

This error occurred when I opened a C++ file that hadn't been open before, which utilized Google Test. I am using CodeGlance3 2.1.1-2021.1.3, on CLion 2021.2.3 build #CL-212.5457.51. It looks like the error is caused here, on line 118:

https://github.com/ranbest/CodeGlance/blob/7185ff1c6dfa50e5b99023a515581df3154b9f09/src/main/java/net/vektah/codeglance/render/Minimap.kt#L117-L119

…which in turn is called here, on line 144:

Here is the stack trace:

I've seen this as well, but in PyCharm 2021.2.3 Build #PY-212.5457.59. Same stack trace, same ClodeGlance plug-in version. A Vagrantfile was the active editor view when it happened.
