Oracle doesn't support 32 bit x86 linux, but we often have to modify platform dependent code as a courtesy to the OpenJDK contributors who do support it. Being able to test 32 bit x86 in mach5 is really helpful. There's a new compilation failure (was just trying to fix the other one in JDK-8254270).

(and a bunch more like this). I hope this is the correct category/subcategory.
