struts2 - Make Struts 2 compatible with Java 8 (legacy ASM 3) -


i'm using struts 2 convention plugin. struts 2 depends on asm 3.3 isn't compatible java 8. fails discover action classes contain lambdas or method references.

the exception:

2014-06-27 18:47:32,958 error main/com.opensymphony.xwork2.util.finder.classfinder: unable read class [my.project.action] java.lang.arrayindexoutofboundsexception: 30305     @ org.objectweb.asm.classreader.readclass(unknown source)     @ org.objectweb.asm.classreader.accept(unknown source)     @ org.objectweb.asm.classreader.accept(unknown source)     @ com.opensymphony.xwork2.util.finder.classfinder.readclassdef(classfinder.java:717)     @ com.opensymphony.xwork2.util.finder.classfinder.<init>(classfinder.java:112)     @ org.apache.struts2.convention.packagebasedactionconfigbuilder.findactions(packagebasedactionconfigbuilder.java:390)     @ org.apache.struts2.convention.packagebasedactionconfigbuilder.buildactionconfigs(packagebasedactionconfigbuilder.java:347)     @ org.apache.struts2.convention.classpathpackageprovider.loadpackages(classpathpackageprovider.java:53)     @ com.opensymphony.xwork2.config.impl.defaultconfiguration.reloadcontainer(defaultconfiguration.java:268)     @ com.opensymphony.xwork2.config.configurationmanager.getconfiguration(configurationmanager.java:67)     @ org.apache.struts2.dispatcher.dispatcher.init_preloadconfiguration(dispatcher.java:445)     @ org.apache.struts2.dispatcher.dispatcher.init(dispatcher.java:489)     @ org.apache.struts2.dispatcher.ng.initoperations.initdispatcher(initoperations.java:74)     @ org.apache.struts2.dispatcher.ng.filter.strutsprepareandexecutefilter.init(strutsprepareandexecutefilter.java:57)

asm 5 seems support java 8 struts isn't binary compatible that.

are there workarounds problems? right i'm considering patching struts/xwork.

guess - had patch thing.
