Solaris 7 (Intel Platform Edition) 8/99 Release Notes

Java Development Kit (JDKTM) Bugs

JDK 1.1.7_07: Java Applications Dump Core When There Is Insufficient Swap Space (4037312, 4042667)

Java applications dump core when there is not enough swap space. Applications sometimes produce the following bus error:

not enough space  

Workaround: Exit other applications running on the system or add more swap space. See the Solaris System Administration Guide for details on adding swap space.

JDK 1.1.7_07: Adjust Colormap To Improve Performance in True-Color Environment (4102599)

Many X-requests in Java applications can cause a slow startup in 8-bit color (TrueColor or PseudoColor) environments. This is apparent on slower systems. A large part of the startup delay is due to the computation of an optimal dithered colormap by the awt library during initialization.

Workaround: Adjust the colormap size computed at initialization by using the environment variable VIRTCUBESIZE. Set it to a power of 2 between 4 and 32. The default value is 32.


JDK 1.2.1_02a: Underlined Text Displays Slowly on a Non-local Host (4170221)

When you set the DISPLAY environment variable to a host other than the one running the virtual machine, underlined text in a network browser displays at a much slower rate than text that is not underlined.

Workaround: Do not use remote display.

JDK 1.2.1_02a: Text Rendering Performance Regression From JDK 1.1.7 and Earlier Releases (4210230)

Text rendering with JDK 1.2 is much slower than with JDK 1.1.7 and earlier releases, including rendering on platforms with Direct Graphics Access support (for example: cg6, ffb frame buffers).

Workaround: Keep socket writes to less than 64 kbytes.
