This gives the WALA maintainers the option of doing future 1.4.5+
releases from of a pre-Gradle branch if these merged Gradle changes
turn out to be more disruptive than expected.

Dalvik bytecode represents 'null' as 0 which may lead to problems
in phi instructions. This variant of TypeInference fixes these
problems by
- tracking whether an SSA value is constant zero and
- ignoring constant zeros in the transfer function of phi instructions
when meeting with non-primitive types
Previously, the various Eclipse projects' Java configurations used
mixtures of 1.6, 1.7, and 1.8. Many were internally inconsistent,
such as requiring 1.7 in "MANIFEST.MF" but 1.6 in the Eclipse JDT
build preferences. The Travis-CI configuration tests against both 1.7
and 1.8, but does not test against 1.6.
Across all projects, the most common version was 1.7. So I'm going to
assume that 1.7 is the intended build target. This commit makes 1.7
the selected version nearly everywhere.
"com.ibm.wala.core.testdata" is the one exception. This specific
project uses a few features only found in 1.8, such as lambda
expressions. Previously, "com.ibm.wala.core.testdata" used 1.7 in
some aspects of its configuration but 1.8 in others. Now it
consistently targets 1.8. I wish this one project didn't need to be
inconsistent with the rest of WALA, but at least now it's consistent
with itself.
(Personally, I'd be happy to target 1.8 only. But my impression
across all of these configuration files is that the WALA developers
still want to be compatible with 1.7. If that is no longer a
requirement, let me know and I will adjust these changes accordingly
to target 1.8 only.)
This change eliminates 11 "There is no 'jre.compilation.profile' build
entry and the project has Java compliance preferences set" warnings
and 13 "The JRE container on the classpath is not a perfect match to
the 'JavaSE-1.7' execution environment" warnings. However, it also
adds 450 "Redundant specification of type arguments <...>" warnings
and 17 "Resource '...' should be managed by try-with-resource"
warnings. So this seems like a net step backward in my wish to reduce
WALA warnings. However, those new warnings concern Java 1.7 language
features that we were not previously using to good effect in projects
that targeted 1.6. If we all agree that we can now target 1.7
instead, then we can use these helpful features as the newly-added
warnings suggest. So I call that a step in the right direction.
This resolves one Eclipse "'...' build entry is missing" warning.
Also update the project configuration to treat this warning as an
error. This should discourage commits that create new instances of
this sort of problem in the future.
a) serializable added for use by Android services
b) test classes refactored to allow Android variants to use JUnit 3
2) shrike instrumentation now uses java.lang.instrument
a) refactoring
b) online variants of call graph tracing
