Just to follow up on this, Max. We basically need a new release of JBoss<br>

was preventing this from working.<br>

so our next release is code freezing tomorrow for JBDS 9 alpha2. I suggest you get that in.<br>

If you need it for JBDS 8/JBoss Tools 4.2.x then that is more of a hassle ...<br>

Haven't heard anything back on this. Is is solved ?<br>
<br>
Anything I can/need to do ?<br>
<br>
/max<br>
<br>
Is there a bug where we can add/share info instead of email ?<br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
How do I reproduce this ?<br>
<br>
I haven't used the latest windup tooling so could use some guidance.<br>
<br>
And I can try take a look after (if lucky during) next week Newcastle<br>
meetup.<br>
<br>
...but my guess is this is more a Lincoln question since he is the<br>
Furnace class loader master mind :)<br>
<br>
...btw. any reason why we don't just run windup externally from the<br>
eclipse tooling and avoid any<br>
of this stuff ?<br>
<br>

Adding Koen and George who may be able to help. Dropping Cat and Burr :-)<br>

Subject: [windup-dev] previously initiated loading for a different type<br>
with name "org/jboss/forge/furnace/util/<u></u>Predicate"<br>
<br>
Lincoln and Jess,<br>
<br>
I have spent another evening trying to defeat this class loading error<br>
with no luck.<br>
<br>
What I have tried:<br>
Debugging CompositeFurnaceClassLoader<br>
changed #loadClass to #findClass as per ClassLoader suggestion, didn't<br>
help<br>
put break point in #findClass to see how many times it is called for<br>
org.jboss.forge.furnace.util.<u></u>Predicate, it is only being called once,<br>
and on that one call it is failing with the LinkageError, this makes 0<br>
sense to me since the error says that it has already been loaded<br>
Tried various combinations of checking to see if the class has already<br>
been loaded, no luck<br>
Tried creating a cache of already loaded classes, didn't help, which<br>
makes sense because the #findClass method (or #loadClass if you dont use my<br>
change) only gets called once for this class.<br>
I have updated the windup-eclipse plugin to use the latest furnace<br>
version, 2.15.2.Final, didn't make a difference<br>
I have updated the windup-eclipse plugin to use the latest Windup 2.2.0<br>
Release, plus my changes to add default constructor to WindupService and<br>
FileService<br>
I have stopped using my custom loadType function I was talking about<br>
earlier, that was a red hearing I believe<br>
I have spent hours googling this error message with no solution path to<br>
be fund<br>
At this point I am totally blocked. I don't know what to try next.<br>
<br>
My latest code is here:<br>
<br>

<a href="https://github.com/itewk/windup/tree/windup-eclipse" target="_blank">https://github.com/itewk/<u></u>windup/tree/windup-eclipse</a>><br>
* as a reminder you can't use SNAPSHOT versions for WINDUP when<br>
compiling the windup eclipse plugin with local changes to Windup because it<br>
will always pull the snapshot from the remote repository and ignore your<br>
local changes, unless using releases in which case maven looks at the local<br>
repo first<br>
<br>
Has anyone been able to try and reproduce this themselves yet?<br>
Has anyone been able to look over my WindupServices class to make sure<br>
I am properly using Forge/Furnace to access Windup?<br>
<br>
I am either doing something really dumb on my end when trying to access<br>
Windup or there is a bug/logic error with the CompositeFurnaceClassLoader.<br>
