Split into a separate issue, originally a part of bug 177970.
Comment 3 Jaroslav Tulach 2010-04-16 16:50:31 UTC 
One report shows that creating presenter for
com.eviware.soapui.netbeans.module.actions.SoapUIMenuAction.getMenuPresenter()
is quite slow.

The other two reports are about
org.openide.awt.AcceleratorBinding.setAccelerator()
which is duplicate of bug 184089

The forth issue 
http://statistics.netbeans.org/exceptions/exception.do?id=369376
is caused by a signed Jar. It blocks classloading in other threads significantly:
java.util.jar.JarFile.initializeVerifier()
it is called from
org.netbeans.lib.uihandler.PasswdEncryption.encrypt(), but I am not sure if that matters.

Given the fact that we don't probably care about eviware.soapui and the other issues are already tracked, let's use this issue as a report for
http://statistics.netbeans.org/exceptions/exception.do?id=369376
assigning to module system, as it seems to be classloader related.

Coming from the ext class loader, nothing to be done outside the JDK.
