5.334. tomcat6 5.334.1. RHBA-2013:0137 - tomcat6 bug fix update Updated tomcat6 packages that fix a bug are now available for Red Hat Enterprise Linux 6. Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. Bug Fix BZ# 852868 When a web application used its own class loader when compiling JSP, a deadlock in Tomcat WebappClassLoader could occur. This update fixes the synchronization bug and external class loaders no longer interfere with WebappClassLoader. Users of tomcat6 are advised to upgrade to these updated packages, which fix this bug. 5.334.2. RHBA-2012:0945 - tomcat6 bug fix and enhancement update Updated tomcat6 packages that fix several bugs and provide an enhancement are now available for Red Hat Enterprise Linux 6. Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. Bug Fixes BZ# 697968 Previously, in certain cases, if "LANG=fr_FR" or "LANG=fr_FR.UTF-8" was set as an environment variable or in "/etc/sysconfig/tomcat6" on 64-bit PowerPC systems, Tomcat may have failed to start correctly. With this update, Tomcat works as expected when LANG is set to "fr_FR" or "fr_FR.UTF-8". BZ# 701759 The "/usr/sbin/tomcat6" wrapper script used a hard-coded path to the "catalina.out" file, which could have caused problems (such as logging init script output) if Tomcat was being run with a user other than "tomcat" and with CATALINA_BASE set to a directory other than the default. With this update, the wrapper script redirects output to USD{CATALINA_BASE}/logs/catalina.out for all "start", "start-security", and "stop" actions. BZ# 748813 Using the URL class coupled with the setChunkedStreamingMode() function caused a null pointer exception error and HTTP response status code 405 was returned. A patch has been applied which adds a check for form data before processing. If the requested body length is zero, a null is returned without further processing. As a result, the error no longer occurs in the scenario described. BZ# 783567 Due to a regression, when a JavaServer Pages (JSP) tag that does not allow JSP Expression Language (EL) expression values (such as struts 2 tags) was used, and one of the attributes was passed a certain value (such as a backslash), the parser threw the following exception: JSP parsing utilizes the directive attribute "deferredSyntaxAllowedAsLiteral" which determines if deferred statements are treated as literals. The default is false. If true, the "#" sign will not be treated as an escape. This update applies an upstream patch and the problem no longer occurs. Enhancement BZ# 782400 With this update, the tomcat6 dependency on redhat-lsb has been removed. Red Hat Enterprise Linux tomcat6 strives to have Linux Standards Base (LSB) compliant systemv init scripts. However, Java has been absent from the list of compliant binaries since 2011. Since Tomcat runs in the Java Virtual Machine (JVM), there is little that can be done in addition to the init script compliance. The redhat-lsb dependency can be removed with very little risk. Users are advised to upgrade to these updated tomcat6 packages, which provide numerous bug fixes and enhancement.
