Building OpenJDK Panama 19

i wanted to build OpenJDK panama for Windows 11 WSL from site:
uname Linux DESKTOP-LCGGQ32 5.10.16.3-microsoft-standard-WSL2 #1 SMP Fri Apr 2 22:23:49 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
git clone https://github.com/openjdk/panama-foreign
cd panama-foreign
On Windows 11 WSL I tried Commands:
./configure --with-boot-jdk=/mnt/c/Tools/jdk-17 --with-libclang="/mnt/c/Tools/LLVM" --with-toolchain-version=2019
Then
make
it fails on make
as shown below:

Sencha CMD problem after macOS Monterrey update

Problem
After update my macOS to Monterrey (12.0.1), I'm with a big problem to start my local projects with ExtJS.
When I execute:
sencha app watch
Get the error:
Sencha Cmd v7.5.0.5

The funny thing is... if run again... the same command (sencha app watch), the error change:

And after each execution, the error keep alternating between those above...
Attempts
1 - JAVA
First, I thinked is something with JAVA version, so I removed all JAVA installed, including brew installed versions.
Also removed all references to JAVA_HOME, and a fresh install of JAVA 8 was maked. No sucess... did it again with JAVA 11, and JAVA 17, without sucess.
Obs. At JAVA 17 the problem changed, but this is because JAVA 17 dont have the javascript processor (javax) anymore.
2 - SENCHA CMD
After the JAVA, have checked Sencha cmd, if has any update or something... my Sencha cmd versio is 7.4.0.39, and for my surprise have a new version (7.5.0.5), but also after update still not working.
Any sugestions?

After talking with some sencha MVP at discord.... have received the following tip:
You must delete the following file:
/Users/user/Library/Application Support/Sencha/Cmd/Update/app.properties
After that workaround, the system works again.
I hope these answer can help someone !!
Update!!!
After some mac os updates deleting the app.properties stop working.
So sencha report to add bypass_lp:true to the app.json

Download JRE 8(support apple sillicon neccessary, ex:zulu/bellsoft), and unzip it.
Edit path in "{your_senchacmd_path}/.install4j/inst_jre.cfg" and "{your_senchacmd_path}/.install4j/pref_jre.cfg" to new JRE path.
Reason: Sencha CMD's included JRE is not compiled for the ARM architecture and even with Rosetta 2.

I've tried everything I can find on how to fix this (drivers are up to date, I have java 8, minecraft 1.12.2).
Normal minecraft works completely fine and my modpacks using twitch launcher work fine, it's only in eclipse that minecraft doesn't start.

Java Eclipse IDE ("For Java Developers" Version, Mac, 64-bit) Crashing Upon Launch

As soon as I double-click my Eclipse application (version stated in title), it crashes, and I receive the usual Mac problem report saying "Eclipse Quit Unexpectedly." The first time I downloaded it, I opened it and it worked fine, but when I quit it and reopened it, it crashed like this — I've tried reinstalling and deleting the previous edition, but to no avail. I'm running OS X El Capitan, 10.11, and Java 8, Update 20, and the most recent version of Eclipse — so I'm up to date on everything.

Eclipse crashing on boot (Mac)

Any help is appreciated. Have a great day folks. :)

There are several solutions for you. You could dual boot windows and install Eclipse and then see if it works. Or you could try other IDEs for example if you are using Eclipse to develop android apps then you could try Android Studio. Or if you are doing java applications then you could try Intellij IDEA.
