Slow "view results in tree" in 5.5 with Java11 (was [VOTE] Release JMeter 5.5 RC1)

Vincent, do you think you could create a reproducer for the issue? (e.g.
share HTML contents)
Do you think you could gather thread dumps (e.g. jstack <jmeter_pid>) while
clicking the "view results" tab?

Hi,
When i need to switch quickly the JDK used by JMeter i set in the
jmeter.bat with :

setlocal
set *JM_LAUNCH*=C:\Java\jdk1.8.0_191\bin\java.exe
rem set JM_LAUNCH=C:\Java\openjdk-11u-11.0.4_11\bin\java.exe
rem set JM_LAUNCH=C:\Java\jdk-11.0.2\bin\java.exe
rem set JM_LAUNCH=C:\Java\jdk-17.0.2\bin\java.exe

and remplace *java *with %JM_LAUNCH%
for /f "tokens=3" %%g in ('%*JM_LAUNCH*% -version 2^>^&1 ^| findstr /i
"version"') do (

Regards.

Could you please try if text.kerning.max_document_size=1 in
jmeter.properties solves the issue?
