-----------------------------------------
Summary: JVMInfo should not use parseFloat() to parse
java.specification.version
Key: DERBY-6518
URL: https://issues.apache.org/jira/browse/DERBY-6518
Project: Derby
Issue Type: Bug
Components: Services
Affects Versions: 10.10.1.1
Reporter: Knut Anders Hatlen
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.
