Jazzer has made fuzzerTestOneInput return void instead of boolean.
This commit adapts the existing Jazzer fuzz targets to this change.
Previously, returning true from a fuzz target would be recorded as a
crash. However, since there is no stack trace in that case, such crashes
cause issues with deduplication. Additionally, the behavior is easy to
replicate with assert or a an if with a throw statement.
The java-example project does not pull in any external dependencies, but
rather consists of three basic Java fuzzers that hit a synthetic bug
after a few seconds. The project can be used to verify that ClusterFuzz
correctly handles JVM fuzz targets.
* ExampleFuzzer fails with an assertion.
* ExampleValueProfileFuzzer fails with an exception after a few seconds,
but only if running in value profile mode.
* ExampleFuzzerNative fails with an ASan report.
