    【已解决】docbook中，用fop生成pdf出错：java.lang.ArrayIndexOutOfBoundsException

    【问题】

    docbook源码写好了，可以正常编译为html。

    也可以编译为fo了，但是使用fop从fo中生成pdf却出错：

    ../../../config/docbook.mk:370: recipe for target `../output/pdf/interrupt_related.pdf’ failed
    make: *** [../output/pdf/interrupt_related.pdf] Error 1

     

    【解决过程】

    1.去看了下所生成的html，很正常，但是却看到一个很特殊的字符：

    ǥ֐ύ

    所以，真的是有点怀疑是这个特殊字符造成的错误。

    以为是不小心对于xml编码转换所照成的字符异常呢，结果去此xml内容的来源的word文件中一看，原来本身word中就是此特殊字符的。

    2.ArrayIndexOutOfBoundsException字面意思是，数组的索引号超出边界了。所以去找找fo或者源码中，哪里可能产生数组的地方。

    3.结果网上也找到了有人遇到类似错误：

    ArrayIndexOutOfBoundsException in LineBreakUtils with LATIN CAPITAL LETTER SHARP S

    所以，就去删除那个特殊字符试试。

    结果的确就解决了此看似怪异的问题，可以正常编译出来pdf了。

    【总结】

    此处出现的java.lang.ArrayIndexOutOfBoundsException，org.apache.fop.text.linebreak.LineBreakUtils.getLineBreakPairProperty方面的错误，是由于一个特殊字符照成的。

    如果不是（细心地）碰巧发现了，还真的很难找到具体原因的。

    总之，以后写docbook源码的时候，只能再仔细一点，以尽量避免此类问题，别无更好的办法了。

     

    【后记】

    后来看了上面帖子：

    ArrayIndexOutOfBoundsException in LineBreakUtils with LATIN CAPITAL LETTER SHARP S

    中的讨论，其是通过把fop从从0.95升级到1.0而解决的此问题。

    但是其实我此处的fop本身就已经是1.0了，但是还是出现了此问题。

    按理来说，是不应该出现这类问题的。

    毕竟，如果本身在UTF-8编码的xml的已经输入了该字符，不论该字符如何特殊，毕竟只要在Unicode范围内，那么就应该可以正常的生成fo文件，而fop也就应该正常的从fo文件生成pdf才对，而不应该出现此错误才对。

    然后去看了下，上面那个特殊字符“ǥ֐ύ”所对应的十六进制是：

    c7 a5 d6 90 cf 8d

    Notepad++中，也是无法显示出对应字符，而显示的是乱码和问号的。

    但是还是觉得既然能在UTF-8的xml中输入了，那么就不应该出现此问题才对。

    有待高手来深入解释。
