[news.eclipse.platform.rcp] WebStart doesnt work in Java 6.0

[Lukas Zapletal <lukas.zapletal@xxxxxxxxx>]

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.java: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:
