<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> | |
