YUICompressor crash - stackoverflow error

Question

I often get what seems to be a stackoverflow error ;-) from YUICompressor. Below is the first part of a thousand lines of errors that occur when trying to compress a CSS stylesheet with a size of 24074 bytes (rather than "Caused by java.lang.StackOverflowError about 8 lines down):

iMac1:src jas$ min ../style2.min.css style2.css Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.yahoo.platform.yui.compressor.Bootstrap.main(Bootstrap.java:21) Caused by: java.lang.StackOverflowError at java.lang.Character.codePointAt(Character.java:2335) at java.util.regex.Pattern$CharProperty.match(Pattern.java:3344) at java.util.regex.Pattern$Branch.match(Pattern.java:4114) 

... (plus another 1021 error lines)

Errors usually occur after adding a couple of lines to a compressed file. Css is great, and works great in uncompressed format. I do not see a specific template for selector types added to the file that cause errors. In this case, adding the following selector to a previously compressed file resulted in errors:

 #thisisatest { margin-left:87px; } 

I am wondering if there is a java flag to increase the stack, which may help. Or, if this is not a problem, what is it?

EDIT:

When I sent this question, it became clear to me that I had to check the java command to see if there was a parameter for increasing the stack. It turns out that this is -Xssn, where "n" is a parameter indicating the size of the stack. Its default value is 512k. So I tried 1024k, but it still led to a stackoverflow. However, trying 2048k works, and I think this might be the solution.

Answer 1

As stated in my edition, the solution was to add parameters to the java command. Under the concept was the error line on the 5th line "at", as shown below:

 at com.yahoo.platform.yui.compressor.Bootstrap.main(Bootstrap.java:21) Caused by: java.lang.StackOverflowError 

Seeing that the problem was "StackOverlowError" ;-), it was suggested to try increasing the stack size. The default value is 512k. My first attempt at 1024k did not work. However, increasing it to 2048k really worked, and I had no additional problems.
