JSP Compilation Difference Between WebLogic 8 and WebLogic 11g (Special Characters) -

we upgraded weblogic 8 weblogic 11g.

we store jsps in database blobs. (yes, know not good. no, wasn't me made decision this.)

now have moved 8 11g, find of jsps stored in database worked fine under weblogic 8 not compile under weblogic 11.

specifically appears 8 used ignore special characters in strings (carriage returns) , 11g has problem this.

does have experience this? there difference in way jsps compile between 2 versions?
