[jira] [Updated] (TAP5-1791) java.lang.StackOverflowError was
thrown at
org.apache.tapestry5.internal.services.ComponentEventLinkEncoderImpl.decodeComponentEventRequest(Request):243
[ https://issues.apache.org/jira/browse/TAP5-1791?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eddie Lo updated TAP5-1791:
---------------------------
Description:
Some some path parameters will cause tapestry getting into infinite loop.
The exact problem is caused by the combination of 3 factors:
* A low priority bug in JVM -- http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6882582
* A regex generated by Tapestry 3.0
^/(((\w(?:\w|-)*)/)*(\w+))(\.(\w+(\.\w+)*))?(\:(\w+))?(/(.*))?
* A long and complex enough path parameter.

When all the the 3 factors are hit, tapestry will get into at
org.apache.tapestry5.internal.services.ComponentEventLinkEncoderImpl.decodeComponentEventRequest(Request):243
and following exception is thrown

There is a limit in java only holding the top 1024 stacks. As the frame is small this time, it have far more that 1024, the bottom is truncated and lost.
However, I used debugger to confirm that it is thrown from org.apache.tapestry5.internal.services.ComponentEventLinkEncoderImpl.decodeComponentEventRequest(Request):243
While the problem is caused by JVM bug (Oracle) and a long complex path parameters (us), it is recommended to also fix this in Tapestry to use a simpler regex.
