PM68388: JSPS COMPILED WITH KEEPGENERATED=TRUE THROW INVALID UNICODE EXCEPTIONS

8.5.0.1: WebSphere Application Server V8.5 Fix Pack 1
8.5.0.2: WebSphere Application Server V8.5 Fix Pack 2

APAR status

• Closed as program error.

Error description

• When a JavaServer Page (JSP) is compiled with the
  keepgenerated=true attribute, the comments generated in the
  resulting java class include information about the JSP's
  looseLibMap and jspCompileClasspath attributes. If the value
  (i.e. path) of either of these attributes contains a "\u", then
  the generated java class throws an "invalid unicode" exception
  due to "\u" being the unicode escape sequence in Java.
  

Local fix

• rename file(s) and folder(s) in those attributes so that they
  do not begin with "\u"
  

Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server            *
  *                  Liberty Profile Version 8.5.0.0 users of    *
  *                  JavaServer Page (JSP) files.                *
  ****************************************************************
  * PROBLEM DESCRIPTION: An invalid unicode exception is         *
  *                      thrown when compiling a JSP file.       *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When the keepgenerated JSP attribute is set to true an invalid
  unicode exception can occur during JSP compilation. This will
  occur if a file or path set in either the looseLibMap or
  jspCompileClasspath JSP attributes contains a "\u" in the
  value.
  An example of this exception is:
  C:\WebSphere\AppServer\profiles\AppSrv01\temp\TestNode01\server1
  \TestEAR\Test.war\_test.java : 142 : Invalid unicode
  

Problem conclusion

• The JSP Container was modified to change a back slash "\" to a
  forward slash "/" when printing out the values of the JSP
  attributes as a Java comment in the generate Java file. These
  values are for display purposes only in the generated Java
  code and the actual value associated with the JSP attributes
  remain unchanged.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.0.1.  Please refer to the Recommended Updates
