SUN_BUG_ID_6322854

public static final boolean SUN_BUG_ID_6322854

See https://bugs.openjdk.java.net/browse/JDK-6322854. java.lang.NullPointerException: Failed to retrieve atom name.

IBM_JDK_DISABLE_COLLECTION_BUG

public static final boolean IBM_JDK_DISABLE_COLLECTION_BUG

IBM JVM 1.4.2 crashes if debugger uses ObjectReference.disableCollection() and ObjectReference.enableCollection().

SLOW_GETTING_CLIPBOARD_CONTENTS

public static final boolean SLOW_GETTING_CLIPBOARD_CONTENTS

See https://bugs.openjdk.java.net/browse/JDK-4818143. The bug is marked as fixed but it actually isn't - Clipboard.getContents(Object) call may hang for up to 10 seconds if clipboard owner is not responding.

REPAINT_MANAGER_LEAK

public static final boolean REPAINT_MANAGER_LEAK

A huge int[] leak through VolatileImages cached in RepaintManager whenever screen configuration changes. For instance screen saver activates or computer goes hibernate. The problem still exists in 1.6 when two (or more) monitors exists

http://bugs.openjdk.java.net/browse/JDK-8041654

SUN_BUG_ID_6486393

public static final boolean SUN_BUG_ID_6486393

Desktop API support on X Window is limited to GNOME (and even there it may work incorrectly). See https://bugs.openjdk.java.net/browse/JDK-6486393.

SUN_BUG_ID_8020443

public static final boolean SUN_BUG_ID_8020443

Java 7 incorrectly calculates screen insets on multi-monitor X Window configurations. See https://bugs.openjdk.java.net/browse/JDK-8020443.

JDK_BUG_ID_8042123

public static final boolean JDK_BUG_ID_8042123

Support default methods in JDI. See JDK-8042123

JDK_BUG_EVENT_CONTROLLER_LEAK

public static final boolean JDK_BUG_EVENT_CONTROLLER_LEAK

Enable a workaround for JDK bug with leaking TargetVM.EventController, see IDEA-163334

JDK_BUG_ID_6822627

JDK_MAC_FONT_STYLE_DETECTION_WORKAROUND

public static final boolean JDK_MAC_FONT_STYLE_DETECTION_WORKAROUND

JDK on Mac detects font style for system fonts based only on their name (PostScript name). This doesn't work for some fonts, which don't use recognizable style suffixes in their names. Corresponding JDK request for enhancement - JDK-8139151.

JDK_MAC_FONT_STYLE_BUG

public static final boolean JDK_MAC_FONT_STYLE_BUG

Older JDK versions could mistakenly use derived italics font, when genuine italic font was available in the system. The issue was fixed in JDK 1.8.0_60 as part of JDK-8064833.
