Hello,

I have a WebStarted RCP app that works under 5.0, but under 6.0 I get exception:

java.lang.NullPointerException
at java.util.Hashtable.put(Unknown Source)
at org.eclipse.core.launcher.WebStartMain.basicRun(WebStartMain .java:58)
at org.eclipse.core.launcher.Main.run(Main.java:977)
at org.eclipse.core.launcher.WebStartMain.main(WebStartMain.jav a:40)

It seems searchFor method returns null here:

//Set the fwk location since the regular lookup would not find it
String fwkURL = searchFor(framework, null);
System.getProperties().put(PROP_FRAMEWORK, fwkURL);
super.basicRun(args);

My JNLP is:

This message has come up before. Search the EclipseZone forum for the hashtable put null message. I believe that it's a missing property such as osgi.framework that's not being said. That aside, I believe that there's also an open bug report at bugs.eclipse.org about JavaWebStart and Java 6 that you might want to search for at https://bugs.eclipse.org.

Thanks. I have also filled a bugreport since NullPointerEx is not a good thing :-)

To save anyone else searching for this (or reporting it) it's been reported as https://bugs.eclipse.org/bugs/show_bug.cgi?id=162097 and has been fixed for the 3.3 stream, and will be available in 3.2.2 as well.

I believe that Eclipse 3.2.2 is nearing release, so waiting for that might be the right thing to do. I'm not sure what else to advise in your case. You could also try running on 3.2.0; the problem (IIRC) was introduced with a renaming of the equinox bundle in 3.2.1.

Ok thank you for your support and have a nice weekend. Btw what do you mean by "try running"? To use startup.jar from that release or to downgrade/upgrade all RCP plugins?

I also have tried 3.2.0 RCP with no luck. Still getting NPE with JRE 6.0.

Yes with WebStart from 1.5.0_10 it works. The provided patch probably doesnt work well with WebStart 1.6.

javawebstart.version=javaws-1.5.0_10
java.version=1.6.0

This bug is not the java 6.0 bug. It is about a problem when trying to find
the osgi bundle by parsing its filename.
The java 6 bug is: https://bugs.eclipse.org/bugs/show_bug.cgi?id=169691
I have attached a version of startup.jar containing the patch attached in
the bug.
