Some TopComponent is deserialized in EDT, using
PersistenceManager.getTopComponentPersistentForID(id, true).

I don't know whether it can be fixed.
Standa, please evaluate. Thank you.

Comment 3 Stanislav Aubrecht 2013-08-15 12:24:19 UTC

Only the latest snapshot shows an actual slowness in NetBeans because TransactionView calls org.netbeans.modules.web.monitor.client.Controller.getTransactions() when deserializing. Please evaluate whether this can be postponed to componentOpened() or componentShowing() methods, thanks.

The remaining two reports are from third-party modules.

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
