I think it’s some setting deep inside javac. I am not sure if it can be overridden or not. I will pass you the logs, and you can try some files for yourself, now that you have a Java code generator 😊. You can exercise your code generator to see if we can get any more examples compiled. But really, I think your reflection loader will solve the issue.
$ sh noncompiled.sh | xargs -L 1 -P 8 javac -J-Xss16m -J-Xmx4096M 2> javacerrors.txt
$ cat noncompiled.sh
find . -name '*.java'| grep -v " "| sed 's/\.java$/.class/'| xargs ls 2>&1| grep "No such file or directory" | awk '{ print $4; }'| sed "s/^'\.\///" | sed "s/\.class':/.java/"
I think the stack overflows were resolved. Attached are JavaCErrors.zip remaining. (336MB)
Maybe try removing tabs? LOL
Are we ready to move to python yet?

Can you increase your memory/stack/heap to the process?

Breaking at each new, or upon discovery of a very large attribute, is possible.

some hints about memory for building with Ant can be found at
Savage Developer Guide: Ant
https://savage.nps.edu/Savage/developers.html#Ant
i.e. ANT_OPTS=-Xss16m -Xmx4096M
These are just pass-through values to the underlying JVM, you can also read about them from console:
javac -help -X

-help Print a synopsis of standard options
-Akey[=value] Options to pass to annotation processors
-X Print a synopsis of nonstandard options
-J<flag> Pass <flag> directly to the runtime system
-Werror Terminate compilation if warnings occur
@<filename> Read options and filenames from file
-Xlint Enable recommended warnings
-Xlint:{all,auxiliaryclass,cast,classfile,deprecation,dep-ann,divzero,empty,fallthrough,finally,options,overloads,overrides,path,processing,rawtypes,serial,static,try,unchecked,varargs,-auxiliaryclass,-cast,-classfile,-deprecation,-dep-ann,-divzero,-empty,-fallthrough,-finally,-options,-overloads,-overrides,-path,-processing,-rawtypes,-serial,-static,-try,-unchecked,-varargs,none} Enable or disable specific warnings
-Xdoclint Enable recommended checks for problems in javadoc comments
-Xdoclint:(all|none|[-]<group>)[/<access>]
Enable or disable specific checks for problems in javadoc comments,
where <group> is one of accessibility, html, missing, reference, or syntax,
and <access> is one of public, protected, package, or private.
-Xbootclasspath/p:<path> Prepend to the bootstrap class path
-Xbootclasspath/a:<path> Append to the bootstrap class path
-Xbootclasspath:<path> Override location of bootstrap class files
-Djava.ext.dirs=<dirs> Override location of installed extensions
-Djava.endorsed.dirs=<dirs> Override location of endorsed standards path
-Xmaxerrs <number> Set the maximum number of errors to print
-Xmaxwarns <number> Set the maximum number of warnings to print
-Xstdout <filename> Redirect standard output
-Xprint Print out a textual representation of specified types
-XprintRounds Print information about rounds of annotation processing
-XprintProcessorInfo Print information about which annotations a processor is asked to process
-Xprefer:{source,newer} Specify which file to read when both a source file and class file are found for an implicitly compiled class
-Xpkginfo:{always,legacy,nonempty} Specify handling of package-info files
-Xplugin:"name args" Name and optional arguments for a plug-in to be run
