Unfortunately, this issue contains reports wtih various root causes. In fact it seems that each report has its own cause and the only reason they are grouped together is the fact that the call tree path passes through explorer API methods...

510817: org.openide.util.lookup.ArrayStorage.cleanUpResult() takes 3,420 ms to complete and during this time org.openide.util.lookup.AbstractLookup.enterStorage() (as a result of a call to org.openide.explorer.ExplorerManager.setSelectedNodes()) blocks in AWT

531539: Recursive calls to org.openide.awt.ContextManager$LSet.resultChanged()	take almost 3s

535102: Most of the time is spent in lookup. Might have something to do with the system kept busy by org.netbeans.modules.parsing.impl.indexing.errors.TaskProvider.updateErrorsInRoot()

561427: A third party code is causing the slowness - com.microchip.mplab.comm.MPLABCommSerialAccess.serialCreateDeviceList[native]() takes 63,683 ms

580171: Finally the one caused by the javacard code. In fact, it is an extremely sluggish method org.netbeans.validation.api.ui.swing.MultilineLabelUI.getMinimumSize()
