Bug#873704: FTBFS with Java 9: keywords

[Chris West]

Source: squareness
Version: 2.3.0
Severity: normal
User: debian-java at lists.debian.org
Usertags: default-java9

This package fails to build with default-jdk pointing to openjdk-9-jdk.
The wiki has some common problems and their solutions:
https://wiki.debian.org/Java/Java9Pitfalls

It uses 'enum' as a keyword, which is supported in -source 1.4, and not
1.5. Java 9 has dropped support for -source below 1.6, and the build
system has automatically migrated everything to 1.6.

Build log:

...

   [javac] /build/squareness-2.3.0/source/org/jvnet/lafplugin/XMLElement.java:481: error: as of release 5, 'enum' is a keyword, and may not be used as an identifier
    [javac]         Enumeration enum = this.entities.keys();
    [javac]                     ^
