[jdk17u-dev] RFR: 8282526: Default icon is not painted properly

[Martin Doerr]

Backport of [JDK-8282526](https://bugs.openjdk.org/browse/JDK-8282526). The prerequisite [JDK-8320692](https://bugs.openjdk.org/browse/JDK-8320692) is already backported to 17.0.13. Applies almost cleanly (except Copyright year update).
