Hi,
This is the fix for JVM crash bug. https://bugs.openjdk.java.net/browse/JDK-8159956 Root Cause : newInsets() method in java.desktop/windows/native/libawt/windows/ThemeReader.cpp file tries to access AwtToolkit::insetsMID method id. In awt headless mode, this method id is not initialized. Trying to access it results in JVM crash. Fix : Creating an object of 'Insets' class is allowed in awt headless mode. (Refer to existing test - test/java/awt/Insets/HeadlessInsets.java) AwtToolkit::insetsMID method is a handle to the constructor of Insets class. The fix for this bug is to Initialize the AwtToolkit::insetsMID even in awt headless mode. This is achieved by invoking native method initIDs() from Toolkit.java static initializer block - this was avoided in headless mode using a check. I have removed this check. Webrev : http://cr.openjdk.java.net/~aghaisas/8159956/webrev.00 Request you to review. Regards, Ajit
