Rick Hillegas commented on DERBY-6518:
--------------------------------------
Heads-up: The 1629234 backport breaks the build of 10.10 on my machine. That is
because the new version of JVMInfo calls java.lang.String.split(). That method
does not appear in CDC/FP 1.1. Releases in the 10.10 family are supposed to run
on that platform. Thanks.
> JVMInfo should not use parseFloat() to parse java.specification.version

> JVMInfo uses parseFloat() to parse the java.specification.version property.
> That won't work correctly if the minor version has more than one digit. It
> should order the versions like this:
> 1.7 < 1.8 < 1.9 < 1.10 < 1.11
> With parseFloat(), they are ordered like this instead:
> 1.10 < 1.11 < 1.7 < 1.8 < 1.9
> The result is that newer Java versions will be classified as older, less
> capable ones, and some functionality might be disabled because Derby thinks
> the platform is not capable of providing it.
