FontManagerFactory class uses reflection to load platform specific FontManager classes from "sun.font.fontmanager" property.
Fix proposes creating FontManager platform specific classes directly in the similar way as it has been already done for GraphicsEnvironment and AWT Toolkit ([JDK-8130266](https://bugs.openjdk.java.net/browse/JDK-8130266) and [JDK-8212700](https://bugs.openjdk.java.net/browse/JDK-8212700)). FontManager is internal jdk class. It is placed in `sun.font` package and java modularization encapsulates FontManager from subclassing and using by a user. The fix reuses PlatformGraphicsInfo to create FontManager platform specific classes. May be FontManager creation code needs to be placed in its own info classes. ------------- Commit messages: - 8273581: Change the mechanism by which JDK loads the platform-specific FontManager class Changes: https://git.openjdk.java.net/jdk/pull/5517/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=5517&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8273581 Stats: 118 lines in 6 files changed: 56 ins; 58 del; 4 mod Patch: https://git.openjdk.java.net/jdk/pull/5517.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5517/head:pull/5517 PR: https://git.openjdk.java.net/jdk/pull/5517
