This one has me stumped ...

I can start the Equinox runtime from JNLP, up to a point. I turn on debug,
try to turn on the console (it doesn't work), and this is what I get in a
log file whenever the runtime tries to start:

!SESSION Wed Sep 19 03:28:10 EDT 2007

!ENTRY org.eclipse.equinox.launcher 4 0 2007-09-19 03:28:10.740

I tried looking at the WebStartMain code, but I don't think the code I
have accessed matches the line numbers in this stack trace (I know because
line 260 should be calling findBundle, but it's not).

I have tried:
* Java 1.4, 1.5, 1.6 (using the 1.6 webstart launcher)
* a config.ini with specified osgi.bundles and an empty one too
* Default signed jars and self signed jars

Here is what my JNLP looks like

----

<?xml version="1.0" encoding="UTF-8"?>

<argument>-noExit</argument>
<argument>-ignoreApp</argument>

<argument>5555</argument>
</application-desc>
</jnlp>

-------------

Any ideas why I get the NPE, I was thinking it might be a missing
dependency. But I can't figure it out. Any help would be appreciated.

Thanks
Augusto

Line 124 from 3.3 corresponds to line 115 from HEAD.

It looks like you have a bundle listed in your osgi.bundles list that wasn't
found in the WebStartMain class loader (see discoverBundles)

I raised https://bugs.eclipse.org/bugs/show_bug.cgi?id=203999
