| <term><emphasis role="bold">Sun Java 1.4.2_12 doesn't serialize CR characters to XML</emphasis></term> |
| <listitem> |
| <para>(Note: Apache UIMA now requires Java 1.5, so this issue is moot.) The XML serialization support in Sun Java 1.4.2_12 doesn't serialize CR characters to |
| XML. As a result, if the document text contains CR characters, XCAS or XMI serialization |
| will cause them to be lost, resulting in incorrect annotation offsets. This is exposed in |
| the DocumentAnalyzer, with the highlighting being incorrect if the input document contains |
| CR characters. </para> |

| <varlistentry id="ugr.issues.jcasgen_java_1.4"> |
| <term><emphasis role="bold">JCasGen merge facility only supports Java levels 1.4 or earlier</emphasis></term> |
| <listitem> |
| <para>JCasGen has a facility to merge in user (hand-coded) changes with the code generated |
| by JCasGen. This merging supports Java 1.4 constructs only. JCasGen generates Java 1.4 |
| compliant code, so as long as any code you change here also only uses Java 1.4 constructs, the |
| merge will work, even if you're using Java 5 or later. |
| If you use syntactic structures particular to Java 5 or later, the merge |
| operation will likely fail to merge properly.</para> |

| <varlistentry id="ugr.issues.libgcj.4.1.2"> |
| <term><emphasis role="bold">Descriptor editor in Eclipse tooling does not work with libgcj 4.1.2</emphasis></term> |
| <listitem> |
| <para>The descriptor editor in the Eclipse tooling does not work with libgcj 4.1.2, and |
| possibly other versions of libgcj. This is apparently due to a bug in the implementation of |
| their XML library, which results in a class cast error. libgcj is used as the default |
| JVM for Eclipse in Ubuntu (and other Linux distributions?). The workaround is to use a |
| different JVM to start Eclipse.</para> |
