Jaroslav Tulach commented on NETBEANS-5914:
-------------------------------------------
The log [^210506 NetBeans Deadlock on Startup 2.txt] seems to indicate the
problem is at
{code:java}
at
org.netbeans.spi.project.support.DelegatingLookupImpl.doDelegate(DelegatingLookupImpl.java:168)
- locked <0x000000061e869218> (a java.util.ArrayList)
at
org.netbeans.spi.project.support.DelegatingLookupImpl.resultChanged(DelegatingLookupImpl.java:84)
{code}
The {{org.netbeans.spi.project.support.DelegatingLookupImpl}} class holds a
lock and calls into unknown code. That's against NetBeans API threading policy.
