JavaとSpringのバージョンはどうなっているでしょうか？

エラーメッセージ下部に

Caused by: org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet

とありますが、これはJavaとSpringのバージョンが非対応の時に出ます。
Java8(jdk1.8.x)とSpring3以下だと対応していません。
Javaのバージョンを下げるかSpringのバージョンを上げると起動できると思います。

バージョンがあってるなら別のところに原因があると思いますが、
バージョンがわからないので確実ではないですが、この投稿から推測できるとしたらこれかなと。

ご回答ありがとうございます！
返信が遅くなり申し訳ありません。
確認してみましたところ
・Java8(jdk1.8)
・Springは4.2.6 RELEASE
でした。
この場合は本来起動できるはずでしょうか？

[xxxAIxxx]

再度確認したところ、ビルド・パスより追加しているspring coreが3.2.3.でした！
(先ほどはMaven依存関係を確認しておりました、申し訳ありません)
こちらを4.1.6に変えてみたところ相談したエラーが解消されたためクローズいたします。
本当にありがとうございました！
