[jira] Commented: (XALANJ-1805) class file generated by xsltc is
too large to run: java.lang.ClassFormatError
[ http://issues.apache.org/jira/browse/XALANJ-1805?page=comments#action_12370541 ]
Henry Zongaro commented on XALANJ-1805:
---------------------------------------
There are two situations in which this problem is most commonly encountered:
1) Stylesheets that contain very large xsl:templates or many global variable declarations that contain lengthy instructions.
2) Stylesheets with many template rules.
The problem described by this bug report sounds like it might fall into the second category. I have requested a test case from Dan Holman, but I've not received a response, so I can't be certain.
The patch for XALANJ-1324 attempts to break up any extremely large methods created for case 1). That patch is unable to do anything for case 2). The byte code generated for xsl:apply-templates would have to be reworked and a more general framework for identifying chunks of byte code that could be moved into new methods would have to be devised.

> Environment: Operating System: Linux
> Platform: PC
> Reporter: Dan Holman

> There is a master stylesheet that imports other stylesheets and they in turn
> import others and so on for a total of 390 xsl files (there are a large number
> of stylesheets partially because some of the files are duplicated for multiple
> language outputs). Using XSLTC from the command line, a single class file is
> generated without error or warning. It has a size of 1.76 MB.

> java -Xmx250MB -classpath $classpath org.apache.xalan.xsltc.cmdline.Compile -x
> xsl/html_master.xsl
> However, it won't transform from the command line.
