Eric Milles commented on GROOVY-8930:
-------------------------------------
Just to add a bit of detail, the default bytecode target for Groovy 2.4 is 1.5;
for Groovy 2.5 it's 1.7; and for Groovy 3.0 it's 1.8. We had been running with
indy compilation under Groovy 2.4 with the posted example and had no issues.
The switch to Groovy 2.5 resulted in verify errors due to the new target
bytecode version.
If the groovy compiler is set with "source=1.8" and "target=1.8", is it
reasonable to expect that the target bytecode version would/should follow suit?
I think we are setting source and target. For sure on our Ant compiles we
are, like this:
{code:xml}
<!-- Create the compiler toolchain under the task name "compile" -->
<taskdef name="groovyc" classname="org.codehaus.groovy.ant.Groovyc"
classpathref="classpath.compile">
</taskdef>
<presetdef name="compile">
<groovyc fork="true" indy="true" includeantruntime="false">
<javac debug="true" source="1.8" target="1.8" />
</groovyc>
</presetdef>
{code}
