A DESCRIPTION OF THE PROBLEM :
See Bug # 8194873

The cause of the bug is right here:

http://hg.openjdk.java.net/jdk/jdk/file/ba545e52b932/src/java.desktop/windows/native/libawt/windows/awt_Component.cpp#l2718

The jint AwtComponent::GetJavaModifiers() function adds a check for VK_RMENU but VK_MENU will already check both ALT keys. This causes TWO bits to be set for the right ALT key which breaks many apps including built-in Swing components.

Get rid of the VK_RMENU check ASAP. Hopefully this can be included in JDK 10. Don't want to wait until JDK 11 !!!

REGRESSION. Last worked in version 8u162

ADDITIONAL REGRESSION INFORMATION:
Was working in Java8


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Remove check for VK_RMENU
