[jira] [Commented] (TAP5-1554) Tapestry fails on OpenJDK with a
java.lang.reflect.GenericSignatureFormatError
[ https://issues.apache.org/jira/browse/TAP5-1554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13053621#comment-13053621 ]
Josh Canfield commented on TAP5-1554:
-------------------------------------
PlasticClassImpl is generating invalid setter signatures in createAccessors so any code that uses @Property fails on openJDK.
It's generating invalid signature in both JDKs, but the OpenJDK implementation of the bean Introspector seems to be parsing the signature instead of using the compiled Method object to determine parameter types.
Turns out it's a typo, the raw field signature was used instead of the generated signature.
