Java error

philja · Today, 05:12 PM

Epubcheck is failing on any epub I try on my Windows box - epubs known to be good on my other machines. And using Sigil 2.6.0.

I bit the bullet yesterday and upgraded my W10 box to W11 since we're getting close to the end of support for W10. All seemed to upgrade without problems but it looks like something fouled up java.

Epubcheck fails with about 1000 lines of error message like this:

Code:

Running EPUBCheck 5.2.1... please wait.
EPUBCheck Java error.
java.lang.StackOverflowError

I don't know how 'thaiopensource' came into the equation. I never had anything to do with thai nor any other asian language.

I checked that java is up to date - version 8 build 461.

Anyone got any ideas how I can sort this?

Yes a java stack overflow failures often happen when you use a 32 bit java virtual machine and do not grow the default stack size. There are two solutions:

Using Doitsu's epubcheck plugin you can grow the stack by setting options in his preferences.

Or simply upgrade to use a 64 bit java virtual machine.

I recommend the latter if your machine supports 64 bit.

I would agree with @KevinH. Since your Windows 11 on X64 install must be 64bit, you should upgrade your Java install to 64bit.
