Editor could not be initialized (First time install).

[Xefreh]

Hi, i'm creating this issue because I don't know why the plugin is not working as expected and throw exceptions that I don't understand.
I installed ecd java decompiler on my eclipse IDE and i've set in file associations ecd as default but when I open a .class file it throws errors.

[Xefreh]

i'm running Windows 11 23H2

[Xefreh]

so I just realized the plugin does decompile classes of librairies but cannot decompile an open class file, if this is normal close my issue thanks and have a nice day.

[jpstotz]

Could you please post the full stack trace in text form of the "Unable to crate part" and the "CoreException" entry? The screenshot you have posted is truncated and does only show classes of Eclipse not of ECD. Thus the relation to ECD is unknown.

[Xefreh]

Sure, here is the stacktrace of the CoreException entry

Looking at the code there is no way to miss this CoreException which means the code seems to be defect by design.

Even looking at the 9 year old code, the CoreException was already in place, so the logic hasn't changed during that time.

ecd/org.sf.feeling.decompiler/src/org/sf/feeling/decompiler/editor/JavaDecompilerClassFileEditor.java

Lines 347 to 351 in 5a472fb

	throw new CoreException( new Status( 8,
	JavaDecompilerPlugin.PLUGIN_ID,
	1,
	"", //$NON-NLS-1$
	null ) );

Commenting out this exception doesn't improve the situation, just the exception changes to java.lang.IllegalStateException: Its not allow to modify JavaModel during ReadOnly action.

From my perspective this is a bug, but as I am not familiar with this code and don't unterstand how it works I don't think that I will be able to fix it.

[diggernet]

I've run into this after upgrading to Eclipse 2024-03. It works in 2023-12. So there's some change in Eclipse that is breaking it. Maybe someone can reach out to Eclipse devs for help?

Thanks for letting me know, ye it would be great.

[nbauma109]

I have a release which is compatible with 2024-03 on my own fork if you want to try.

thanks I'm going to try that later, did you made a PR ?

[nbauma109]

No, unfortunately, I have too many changes and a lot of conflicts.

[scmod]

perhaps an eclipse bug?
[https://github.com/eclipse-jdt/eclipse.jdt.ui/issues/1443](eclipse issue)

currently uncheck the eclipse member sort may solve the problem, but a restart or uncheck the reuse code buffer then reopen class file is needed
my stacktrace is different

I confirm that when:

• downloading a fresh eclipse package (2024-06)
• installing this plugin
• opening a .class file

=> the editor is throwing the error mentioned above:

java.lang.IllegalStateException: Its not allow to modify JavaModel during ReadOnly action. delta=Java Model[*]: {CHILDREN}
	 [*]: {CHILDREN}

We see the same exception as above with eclipse 2024-06.

I have seen this IllegalStateException but it seems to be influenced by VMware (I run Eclipse in Ubunu 22.04 client vm). When I disabled VM 3D Hardware acceleration this exception went away (I still cannot make the decompiler work). I have switched to use Xorg instead of Wayland, and I have also added this variable to my .profile:

# disable hardware acceleration for webkit
export WEBKIT_DISABLE_COMPOSITING_MODE=1

I am using Eclipse 2024-06. I have used this decompiler on Eclipse 23-03 previously and it works fine there.

In my case, I use eclipse from WSL, i.e. virtualization. Corroborating w/ your input: it seems to be related to running Eclipse virtualized?
