Steps to reproduce:
- have jdk6 & jdk7 installed on your system
- install PHP bundle from trunk - NetBeans IDE Dev (Build 201109040600) and select jdk7 to be used during the installation
- start NetBeans, create PHP project, close NetBeans
- change jdk in netbeans.conf to jdk6
- start NetBeans
=> NetBeans won't start and exception is shown (see log)

If I switch back to jdk7, it works fine again. If I don't want to switch, I had to use new user dir and then NetBeans will work again with jdk6.



Product Version: NetBeans IDE Dev (Build 201109040600)
Java: 1.7.0; Java HotSpot(TM) Client VM 21.0-b17
System: Windows 7 version 6.1 running on x86; Cp1252; en_US (nb)
Comment 1 Jaroslav Tulach 2011-09-12 13:40:35 UTC 
reproduced on build 201109040600
Comment 2 Jaroslav Tulach 2011-09-12 14:01:11 UTC 
Caused by duplicated singleton: org.eclipse.osgi from Netbinox and additional one provided by Mylyn.
Comment 3 Jaroslav Tulach 2011-09-12 14:06:38 UTC 
Fixed at least in revision
http://hg.netbeans.org/main-golden/rev/c4d262f630a7
probably sooner.
