Bernard commented on NETBEANS-1824:
-----------------------------------
Thank you very much, the offending code is an old version of dl4j
To see the error,
# Start Apache NetBeans 11.0 with a new user directory and cache directory.
# Use GIT to download from https://github.com/deeplearning4j/dl4j-examples the
master branch on 18/04/2017, 12:48:59 AM and compile the modules.
# Inspect the log
The current version of the examples does not have the problem. So in a
nutshell, IDE versions 9/0, 10.0, 11.0 are throwing exceptions with projects
that refer to dl4j code of that time, while IDE version 8,2 doesn't.
As far as my projects are concerned, they wouldn't refer to the examples
project, but the examples project should be a good enough test case as a start
if it is of interest. If you need the exact copy of the examples, I can attach
a zip file. Please feel free to request.

> Issue Type: Bug

> java.lang.ClassNotFoundException: com.sun.tools.javac.code.TypeTags
> My IDE is frozen with NetBeans using CPU on all 8 cores at 100%.
> The log is filled up with messages as below.
> On the screen, there is a dialog "Save (Not Responding)" where it asks to
> confirm saving 2 Java files. I clicked "Save All" but this kept popping up
> unresponsive after the IDE lost focus and then re-gained focus in a cycle
> many times.
> I don't know what the primary issue is - the HIG CPU usage for perhaps
> another reason or the errors in the log file. I cannot do anything at all
> because JVisualVM cannot get a handle on NetBeans and waits forever computing
> a description.
> Therefore, I would think that solving the ClassNotFoundException has the
> higher priority. It fills up the logs and prevents discovery of other issues.
> All 3 log files are full of that exception.
>
> BTW Jira is too hard to use, I cannot search with it in a meaningful way. If
> I search for anything, then I get results from other projects as well as
> default which is stupid. The lack of an automatic duplicate search alone has
> the potential to kill the entire project. Atlassian Jira is the wrong tool
> for NetBeans. NetBeans needs bugzilla,
