compilerArg for batch compiler/PDE Build -warn:-raw not working [message #1766896]

I'm using Eclipse Neon 4.6.3 with Java 8.121.
During our headless builds, I'm getting warnings about raw types, e.g.,

Type safety: The method fireValueChange(ValueDiff) belongs to the raw type AbstractObservableValue. References to generic type AbstractObservableValue<T> should be parameterized

I'd like to ignore these for the moment, so I changed the 'compilerArg' entry in build.properties to be something like:

compilerArg="-warn:-raw,+null,nullDereference,unusedAllocation

but that doesn't suppress the warnings. Oddly, this did:

compilerArg="-warn:none,+null,nullDereference,unusedAllocation

but there's a message in the output:

invalid warning token: 'none'. Ignoring warning and compiling

How does one get this to work? Or is it a bug?

Is this still relevant?
Directly from a shell prompt I cannot reproduce. Maybe s.t. is not correctly passed from PDE/build to the batch compiler?
Can you see the actual command line of the compiler invocation?

I'm invoking the build with

/c/Program Files/Java/jdk1.8.0_141/bin/java' -jar /d/eclipse.neon.x86_64/plugins/org.eclipse.equinox.launcher_1.3.201.v20161025-1711.jar -application org.eclipse.ant.core.antRunner -buildfile /d/eclipse.neon.x86_64/plugins/org.eclipse.pde.build_3.9.200.v20160204-0642/scripts/productBuild/productBuild.xml -Dbuilder=/c/views/integ3/itek/JavaProjects/projects/rmps/buildConfig -Dbase=/d -DbaseLocation=/d/eclipse.neon.x86_64 '-DSO_PREFIX= ' -DSO_SUFFIX=dll -data ./workspace -Dbaseos=win32 -Dbasews=win32 -Dbasearch=x86_64 -Dconfigs=win32,win32,x86_64 -DbuildType=R -DbuildId=TestBuild -DarchiveNamePrefix=com.goodrich.rmps -DarchivePrefix=RMPS -DbuildDirectory=/c/views/integ3/itek/JavaProjects/projects/rmps -Dproduct=/c/views/integ3/itek/JavaProjects/projects/rmps/plugins/com.goodrich.rmps.db110.productLine.product/rmps.productLine.db110.product

The compilerArg value is specified in "/c/views/integ3/itek/JavaProjects/projects/rmps/buildConfig/build.properties":

compilerArg="-warn:-raw,-deprecation,-enumSwitch,+null,nullDereference,unusedAllocation,unusedThrown,unusedImport,deadCode,hiding,uselessTypeCheck,syncOverride,semicolon,conditionAssign,fallthrough"

You show the command line of the ant invocation. Unfortunately, this doesn't show how the compiler (ecj) is invoked.
Perhaps you need to pass some verbose flag to ant in order to see that?
