Stack overflow with the Oracle runtime environment

[ways2read]

I'm on a Windows machine running Java(TM) SE Runtime Environment (build 1.8.0_471-b09) from Oracle.

I run EPUBCheck, messages fly past and then I see the happy result:

Messages: 0 fatals / 0 errors / 0 warnings / 0 infos
However, if I think to scroll all the way back to the top of the messages I see that I had a stack overflow:

>java -jar epubcheck.jar 9780472901234.epub
Validating using EPUB version 3.3 rules.
java.lang.StackOverflowError
        at com.thaiopensource.relaxng.pattern.InterleavePattern.checkRestrictions(InterleavePattern.java:35)
        at com.thaiopensource.relaxng.pattern.InterleavePattern.checkRestrictions(InterleavePattern.java:35)

So I run EPUBCheck with -Xss to increase the thread stack size:

java -Xss10m -jar epubcheck.jar 9780472901234.epub

and the result is:

Check finished with errors
Messages: 1 fatal / 238 errors / 562 warnings / 0 infos

I guess three parts to this issue:

• There was a stack overflow using the 32-bit JRE from java.com (the default offering)
• I did not know there was a stack overflow until I happened to scroll all the way to the top.
• What I actually saw was that EPUBCheck reported that there were 0 issues.

The stack overflow issue is known, especially I guess with older JVMs. But it should definitely raise an error message early on instead of giving a false negative.

I will look into it!
