PropertySetter should ignore GCJ installations
----------------------------------------------
Key: DERBY-5189
URL: https://issues.apache.org/jira/browse/DERBY-5189
Project: Derby
Issue Type: Improvement
Components: Build tools
Affects Versions: 10.8.1.1
Reporter: Knut Anders Hatlen
Assignee: Knut Anders Hatlen
Many Linux platforms come with GCJ installed. GCJ implements most of the Java
SE API, but not all of it, so it cannot be used to build Derby. Unfortunately,
PropertySetter sometimes get confused by it and constructs a compile classpath
using GCJ's libraries.
For example, on a machine running Debian 6.0.1, I have the sun-java6-jdk
package as well as the gcj-jdk package installed. When running ant to build
Derby (with no ~/ant.properties), I get these compile classpaths constructed:
printCompilerProperties:
[echo] After setting properties: compilerPropsAlreadySet = true
[echo] After setting properties: compilerLevel16 = 1.6
[echo] After setting properties: jsr169compile.classpath =
/home/kah/derby/trunk/classes/stubs/jsr169:/usr/lib/jvm/java-1.5.0-gcj-4.4/jre/lib/rt.ja

java-6-sun-1.6.0.24/jre/lib/rt.jar
Since java15compile.classpath is based on GCJ, and GCJ lacks some classes in
the javax.management.remote package, the build fails when it gets to the JMX
tests:
compile_jdk15:

PropertySetter should ignore GCJ installations to prevent this problem. If it
hadn't found GCJ, it would have constructed java15compile.classpath from
java16compile.classpath, and the build would have succeeded.
