推荐答案

当所有Java Swing应用程序都静默崩溃时，我遇到了问题.尝试从命令行启动后，出现以下异常:

I had problem when all java Swing apps crashed silently. After trying to launch from command line got the following exception:

Caused by: java.lang.IllegalArgumentException: 181193932 incompatible with Text-specific LCD contrast key

如 JDK-6503988 所述，问题是与 ClearType 注册表设置

As it's said in JDK-6503988, the problem is connected with ClearType registry setting FontSmoothingGamma.

可以通过运行"调整ClearType文本来解决此问题"(通过控制面板( cttune.exe ))或通过

This can be fixed by running "Adjust ClearType text" from Control panel (cttune.exe) or by changing the registry directly:

reg add "HKEY_CURRENT_USER\Control Panel\Desktop" /t REG_DWORD /v FontSmoothingGamma /d 1024 /f

可能需要重新启动才能使更改生效.

A reboot may be needed for changes to take the effect.
