Subject: ugh. updating XML .classpath parser to handle any number of attributes
X-Git-Tag: V1_1_0_RC2~156
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=887932498cd5bd1c88f5849a1244caa36f280838;p=aspectj.git

ugh. updating XML .classpath parser to handle any number of attributes
still does not handle quoted spaces or nested entities.
Also updated for new attribute names in 2.1?
