After casting my vote for 12.1 vc1, I encountered 4696 again (on

This is starting to worry me. I just saw the same thing when upgrading
one of my laptops to 12.1-vc1. This is on first start. The only thing
I did that might have been naughty was to rename the beta4 user and
cache dirs to 12.1.
I was able to close NetBeans normally. Took another thread dump first
and put it to JIRA.
Here's the deadlock, note that parsing.api.ParserManager.parse is one at
a time
(full thread dumps in issue report)
A task that's parsing is waiting for projects to finish opening.
Project opener is waiting to parse.
The maven stuff from ProjectOpener looks pretty suspicious, but IDK?????
If it only happens with the html stuff, then maybe the rule is that
a parser isn't supposed to wait for the ProjectOpener.
=== a parsing task
Some Random Task does parsing, invokes
at org.netbeans.modules.parsing.api.ParserManager.parse
(ParserManager.java:81)
and then does
at org.netbeans.modules.html.editor.api.gsf.HtmlParserResult.root
(HtmlParserResult.java:119)
which ends up doing
at
org.netbeans.modules.project.ui.OpenProjectList$LoadOpenProjects.get
(OpenProjectList.java:576)
and this OpenProjectList$LoadOpenProjects.get() wait for opening to
complete
=== "Load Open Projects"
at org.netbeans.spi.java.project.support.CompilerOptionsQueryMerger
$CompilerOptionsQueryImpl$ResultImpl.lambda$checkProviders$4
(CompilerOptionsQueryMerger.java:184)
goes into some maven specific code
at
org.netbeans.modules.maven.queries.UnitTestsCompilerOptionsQueryImpl
$ResultImpl.getArguments
(UnitTestsCompilerOptionsQueryImpl.java:155)
which ends up at
at
org.netbeans.modules.maven.queries.UnitTestsCompilerOptionsQueryImpl
$ResultImpl.getModuleName
(UnitTestsCompilerOptionsQueryImpl.java:289)
and then
at org.netbeans.modules.parsing.api.ParserManager.parse
(ParserManager.java:81)
