[DERBY-6854] Make it possible to run Derby tests on early access versions of JDK 9

• Type: Improvement
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 10.12.1.1
• Component/s: Build tools
• Urgency: Normal

Description

Early access versions of JDK 9 (build 100) have "9-ea" as the java.version and "9" as the java.specification.version. This confuses the JavaVersionHolder class which the regression tests use in order to determine the vm level. At a minimum, we need to make JavaVersionHolder recognize these early access strings.

This issue can be left open even after a fix is applied because we have no idea how java.version and java.specification.version are going to evolve over the remaining development cycle for JDK 9.
