Subject [jira] [Commented] (GROOVY-8930) JVM verification fails when using static interface method from inside CompileStatic groovy
Date Thu, 20 Dec 2018 16:26:00 GMT

    [ https://issues.apache.org/jira/browse/GROOVY-8930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16725999#comment-16725999
] 

Eric Milles commented on GROOVY-8930:
-------------------------------------

Another note: the target bytecode attribute of Ant Groovyc only supports 1.4 and 1.5 in Groovy
2.4.  This has since been fixed in Groovy 2.5+.

{code:java}
    /**
     * Sets the bytecode compatibility mode
     *
     * @param version the bytecode compatibility mode
     */
    public void setTargetBytecode(String version) {
        if (CompilerConfiguration.PRE_JDK5.equals(version) || CompilerConfiguration.POST_JDK5.equals(version))
{
            this.targetBytecode = version;
        }
    }

    /**
     * Retrieves the compiler bytecode compatibility mode.
     *
     * @return bytecode compatibility mode. Can be either <tt>1.5</tt> or <tt>1.4</tt>.
     */
    public String getTargetBytecode() {
        return this.targetBytecode;
    }
{code}
