FileMisc throws an unexpected exception when a download fails

[yohoe]

FileMisc.download(..) throws an IllegalArgumentException when a download fails (e.g. 404), but PdeInstallation and P2BootstrapInstallation expect it to throw FileNotFoundExcpetion in order to try alternative uris.

Workaround in my case is to append the version to goomph_override_p2bootstrapUrl so that the first try is successful, but this is less flexible.

Thanks for reporting, PR's welcome.

The EquoIDE plugins use okhttp instead of the janky FileMisc stuff, this issue is almost certain solved if you migrate to dev.equo.ide or dev.equo.p2deps. https://github.com/equodev/equo-ide/tree/main/plugin-gradle
