| 26 | <dt>No more failures in Maxima's test suite</dt> |
|---|
| 27 | <dd>Working together with the developers from the Maxima program, we've been |
|---|
| 28 | able to identify the causes for the last few remaining failures and |
|---|
| 29 | apply fixes - mostly to ABCL, but some in Maxima too. Thanks guys!</dd> |
|---|
| 30 | <dt>Fixes to stop JRockit JVM's optimizer from crashing</dt> |
|---|
| 31 | <dd>Some specific aspects of the byte code we generated was a problem |
|---|
| 32 | for the optimizer in JRockit JVM. JRockit has been fixed, but the release |
|---|
| 33 | won't be out for some time. Since we identified the offending code, we |
|---|
| 34 | decided to change our byte code as well.</dd> |
|---|
| 35 | <dt>Fixes to CLOS thread safety.</dt> |
|---|
| 36 | <dd>Taking advantage of the java.util.concurrent package, we have both been |
|---|
| 37 | able to eliminate many synchronized blocks, reducing chances for |
|---|
| 38 | contention as well as increasing protection by using types with built-in |
|---|
| 39 | protection. |
|---|

|---|
| 41 | <dt>Updated ASDF2</dt> |
|---|
| 42 | <dd>ASDF2 has been updated to its latest version 2.010.1</dd> |
|---|
| 43 | <dt>Experimental support for the long form of DEFINE-METHOD-COMBINATION</dt> |
|---|
| 44 | <dd>Support for the long form of DEFINE-METHOD-COMBINATION has been added, |
|---|
| 45 | however, this support is derived from Sacla and XCL, which probably means |
|---|
| 46 | that the code hasn't been excercised all that much and does contain |
|---|
| 47 | bugs. You're strongly urged to help debug and define test-cases in order |
|---|
| 48 | to fix any issues in the code.</dd> |
|---|
| 49 | <dt>A new (generic) class writer</dt> |
|---|
| 50 | <dd>Our compiler used to contain code to generate class files which exactly |
|---|
| 51 | match ABCL's usage patterns. However, in order to expand ABCL's compiler |
|---|
| 52 | possibilities - as well as providing support for extension of Java classes |
|---|
| 53 | at runtime - a more generic class file generator is required. We have one |
|---|
| 54 | now! </dd> |
