Manual JCK test api/javax_swing/interactive/JSplitPaneTests.html#JSplitPane fails with Nimbus LaF.
Testcases check the behavior of JSplitPane created with the different constructors,
 it verifies that the splitpane's child components are not redrawn continuously as the divider changes position.
It works without Nimbus LaF and has no effect with Nimbus.
Next testcases failed:
JSplitPaneTest0001: Failed. JSplitPane created by JSplitPane()
JSplitPaneTest0002: Failed. JSplitPane created by JSplitPane(JSplitPane.HORIZONTAL_SPLIT)
JSplitPaneTest0003: Failed. JSplitPane created by JSplitPane(JSplitPane.VERTICAL_SPLIT)
JSplitPaneTest0005: Failed. JSplitPane created by JSplitPane(int,Component,Component)
