I fixed the title and I added an exclusion of the test jdk/java/awt/font/JNICheck/FreeTypeScalerJNICheck.java for Windows debug builds because these could bring up the assertions in headless test environments.

This kind:
`*********************`
`AWT Assertion Failure`
`*********************`
`hBM != 0`
`File '...\\openjdk-21u-dev-windows_x86_64-dbg\\jdk\\src\\java.desktop\\windows\\native\\libawt\\windows\\awt_Win32GraphicsDevice.cpp', at line 185
GetLastError() is 6 : The handle is invalid.`

`Do you want to break into the debugger?`
`*********************`
